Top 10 Best Expository Essays on Wild Animals (Grade 9)

Throughout history, lions have been featured in classic literature like Narnia and films such as The Lion King, symbolizing power and bravery. Known as the 'king of the jungle,' lions are often regarded as the strongest and most skilled beasts in nature. Lions once roamed the vast plains of the world, but due to human population growth, deforestation, and the destruction of habitats, they now remain in small, scattered areas, primarily in Africa.

There are many subspecies of lions, with the African lion being the most common. Additionally, the Asiatic lion can be found in the Gir Forest of India, and rare white lions reside in Timbavati, South Africa. While white lions are not widely discussed due to their rarity, they still exist. Their white coat is caused by a recessive gene, which hinders their ability to hunt as it makes them visible in the wild. Lions have long been symbols of royalty and nobility.

Lions also appear in Chinese art, despite never having lived in China. No animal is depicted more in art and literature than the lion. According to C. A. W. Guggisberg in his book 'Simba,' lions are mentioned 130 times in the Bible, and they are often seen in prehistoric cave paintings.

In Western astrology, the lion (Leo) is one of the 12 zodiac signs, symbolizing the 'Leo' constellation. Legend has it that the goddess Hera, in mourning for her lion's death while on a mission, transformed its soul into a cluster of stars.

Lions belong to the cat family but have a larger, more robust appearance compared to their relatives. An adult male lion weighs about 189 kg and stands around 1.2 meters tall, while females weigh around 126 kg and stand about 1.1 meters tall. The heaviest lion ever recorded weighed 272 kg, found in the mountains of Kenya.

Lions are large 'big cats' with a sandy coat that camouflages perfectly with the grasslands, allowing them to hunt stealthily. Their bellies and sides are white, especially in females. The insides of their ears and the tuft of fur at the end of their tails are dark brown or black.

An adult lion has 30 teeth, including four canine teeth designed for biting and tearing food. They also use sharp claws for hunting and self-defense.

The lion's roar is one of its most distinctive features, starting at one year old. Roaring not only marks their territory but also communicates with other lions in the pride. It is also a sign of dominance and a warning to rival lions.

The most noticeable difference between male and female lions is the mane. Only males grow a mane, which protects them from bites and scratches during fights with rivals. The mane color can range from black to golden and covers the face, neck, and sometimes extends along the lion's back.

Lions are exceptional predators, living in prides that usually hunt large, dangerous prey. A pride typically consists of 30 to 40 lions, with their territory spanning from 20 to 400 square kilometers. Most of the pride consists of females and their cubs, with only a few males. The dominant male leads and protects the pride.

Hunting is a daily task for lions, with their prey including zebras, buffaloes, giraffes, hippopotamuses, and even young elephants. When hunting alone, they target smaller animals such as antelopes and wild boars. Lions living near coastlines may also hunt seals. When hunting alone, they kill prey by biting the neck to break it or disrupt the circulatory system. When hunting in a group, they can subdue large prey while others suffocate it by blocking its airway. Lions generally don't prefer hunting alone, and they often drive away smaller predators or competitors from a kill. Lions are also often chased away from their prey by hyena packs or wild dogs due to their greater numbers. Like other members of the cat family, lions have excellent night vision, which makes them highly agile at night. They can sleep for more than 20 hours a day.

However, today, lions face the threat of extinction due to illegal poaching and hunting. It is critical to adopt proper policies to preserve and protect the lion population.

In Eastern culture, tigers are often referred to as the "King of the Mountains" or "Old Thirty". Their immense strength and expert hunting abilities have earned them these awe-inspiring titles. However, not many people fully understand the distinctive traits of this wild animal.

The tiger (also known as the "côte" or "tiger cat") is a mammal from the cat family. This is why some people jokingly call it a "giant cat." Unlike domestic cats, tigers are excellent swimmers and are often seen bathing in ponds, lakes, or rivers. However, tigers are not as skilled at climbing as domestic cats.

Historically, tigers have been known as fierce predators that hunt and consume live prey. Their primary diet consists of herbivorous animals like deer, boars, buffalo, and others. In Vietnam, there are many stories about tigers appearing on New Year's Eve to capture livestock like cattle and buffalo. The name "Old Thirty" comes from this. Tigers typically hunt alone and prefer ambush tactics, overpowering their prey from all angles and finishing them off with a bite to the neck, severing major arteries or veins to bring an immediate death. Additionally, their swimming ability allows them to attack prey even while the prey is in the water.

Tigers primarily inhabit forests and grasslands, areas that provide ideal environments for them to conceal themselves. Their fur is usually golden or reddish-orange with white spots on their body, neck, chest, and even inside their legs. However, their most effective camouflage comes from their stripes. Tiger stripes are typically brown, gray, or black. The pattern and number of stripes vary among tiger subspecies, but generally, there are around 100 stripes per tiger. These stripes enable tigers to blend into dense forest vegetation and deceive their prey.

Historically, tigers ranged from Russia, Iran, Afghanistan, India, China, to Southeast Asia. However, their habitats have been significantly reduced due to widespread hunting by humans. Tigers have been hunted for their pelts, bones, or organs, which are used in traditional medicines. Many people illegally hunt and kill tigers, destroying their habitats, which has led to a dramatic decrease in tiger populations. Certain subspecies, such as the Javan tiger, Bali tiger, and Caspian tiger, have gone extinct. Consequently, tigers are now listed as an endangered species.

In conclusion, the tiger is a magnificent predator with superior strength, one of the most skilled hunters in the animal kingdom. Yet, this majestic species is now at risk of extinction due to the rampant illegal hunting by humans. Therefore, it is crucial that we adopt effective conservation policies to protect and sustain the tiger population.

In the wild, tigers are among the most efficient and deadly hunters. With their massive yet sleek bodies, extraordinary strength, and remarkable speed, tigers have become a source of fear for many creatures, including humans.

The tiger (also known as the "côte," "Old Thirty," or "King of the Forest") is a carnivorous mammal from the big cat family, Panthera. The ancestors of modern tigers first appeared in East Asia around 2 million years ago. From there, tigers gradually expanded to the dense forests and rivers of the Northwest, later moving into Southwest Asia.

Another branch of tigers migrated southward into Southeast Asia, the Indian subcontinent, and the Indonesian archipelago. As tigers evolved and sought new food sources and territories, they spread across the globe, forming the various subspecies we know today.

On average, an adult tiger weighs between 100 and 300 kilograms. Tigers possess a large yet lean body structure, perfectly suited for agile movement. This physique aligns well with their wild, predatory nature.

The entire body of a tiger is covered in soft fur, which is typically orange, gray, or white, adorned with dark, wavy stripes. Most tiger species have stripes that range from brownish-gray to black. White tigers have fewer stripes. The pattern and density of stripes vary among species, but most tigers have over 100 stripes.

This unique coloration and patterning make the tiger a striking figure in the animal kingdom. The golden-orange fur, coupled with black stripes, helps tigers blend into dry grass and conceal themselves as they approach their prey unnoticed. Tigers have small yet sensitive ears that are constantly upright, honing in on sounds. Their long canine teeth and powerful jaws can easily crush bones, while their sharp claws are formidable tools that help tigers swiftly overpower large prey such as wild buffalo, antelope, or deer. When walking, a tiger's claws retract into its paws, leaving only the thick pads in contact with the ground, allowing for stealthy and graceful movement. Tigers also have exceptional night vision, enabling them to hunt effectively during the evening and early morning hours, while spending the remainder of the day hiding in deep forest cover.

In terms of physical power, tigers are unmatched. When hunting, a tiger can reach speeds of 40 km/h. They have the strength to knock down and kill prey that is double their own weight. Their ability to ambush and swiftly kill makes them the most effective hunters in the animal world.

Overall, tigers embody all the superior traits of a predator. With their immense strength, they are one of the most fearsome hunters on the planet. While tiger populations have dwindled in recent years, they remain dominant and highly skilled within their forested habitats. Most tigers reside in dense forests and grasslands, environments where their camouflage abilities are most effective. The most common habitats are in the jungles of Asia, India, and Southeast Asia.

Tigers typically hunt alone, although there are occasional instances where they cooperate to take down larger prey. Their diet primarily consists of medium-sized herbivores such as deer, wild boar, and buffalo, though they can also catch smaller or larger animals when the opportunity arises. A typical tiger can consume up to 27 kilograms of meat in a single meal.

Tigers are mammals that give birth to cubs. A typical litter consists of 2-3 cubs, who live with their mother for 2-3 years before becoming independent. By this age, they are fully grown and capable of reproduction. In captivity, tigers can live up to 20 years, but in the wild, their lifespan ranges from 10 to 15 years.

In the wild, tigers play a crucial role as apex predators in the food chain. Their presence helps regulate the populations of herbivores and other carnivores, maintaining balance within the ecosystem.

Crocodiles are common in tropical regions, particularly where rivers, lakes, and swamps abound. With their fierce hunting nature, terrifying killing skills, and intimidating presence, crocodiles command both reverence and fear from humans.

Today, due to habitat changes and intense hunting pressures, the number of crocodiles worldwide is dwindling. However, they still cause tragic fatalities each year.

Crocodiles are carnivorous reptiles that primarily inhabit water. They have existed on Earth for about 84 million years, dating back to the Late Cretaceous period. The term "crocodile" in Vietnamese refers to true crocodiles, as well as short and long-snouted species. It is also used to describe their prehistoric relatives, such as the "marine crocodile". For a long time, they dominated the Earth.

Among reptiles, crocodiles are the largest and most complex in structure. Their elongated body is covered in tough, bony scales. The body is divided into three distinct parts: the head, body, and tail. The head of a crocodile makes up about a third of its total length. The flat head, long snout, and powerful jaws with sharp, inward-curved teeth make them deadly predators. The eyes are small and positioned on top of the head, giving them poor vision, but they are excellent at detecting movements in the water. Their tongue is thick and immobile, and both nostrils and ears have water-resistant membranes, allowing crocodiles to stay submerged for long periods. Their bodies are large, with short front limbs and longer hind limbs. Their webbed feet act like paddles, aiding in swift and silent swimming. The long, strong tail acts as a rudder for smooth navigation in water.

The size of crocodiles varies greatly between species and age. Some large species can reach lengths of 5 to 6 meters and weigh up to 1,200 kilograms. However, hatchlings are only around 20 cm long and weigh just a few grams. Some species in Australia can grow to enormous sizes, becoming a terrifying presence for both aquatic life and humans.

Crocodiles thrive in water and are found across the tropical regions of the world. Swamps, ponds, rivers, and streams are their typical habitats. As carnivores, they are skilled hunters with a diverse diet, consuming fish and mammals, both alive and dead. They attack anything that moves in the water and are highly sensitive to blood. When a crocodile detects an injury in its prey, it relentlessly pursues until the prey is subdued.

Their hunting technique is unique. Once a crocodile captures its prey, it spins its body to drag the prey underwater. This powerful spin can break bones, killing the prey instantly. Afterward, they tear the prey apart and consume it beneath the water's surface.

As for reproduction, all crocodiles are egg-layers. A single clutch can consist of 30 to 70 eggs. The mother guards her nest diligently throughout the incubation period, not hunting, but remaining nearby. When the eggs are close to hatching, the mother helps by digging and bringing the hatchlings to water. The newborn crocodiles, weighing a few hundred grams, are cared for by their mother for the first few weeks before becoming independent. By 4 or 5 years of age, crocodiles are fully mature and begin to reproduce. Adult crocodiles can grow to over 6 meters long and weigh around 1,000 kilograms. They can live to be over 100 years old.

In 1997, a 115-year-old crocodile was discovered in Russia, the oldest known specimen. Throughout their lives, crocodiles rarely leave the water, and they are clumsy on land.

In nature, crocodiles are feared and highly effective predators. They lie in wait patiently for their prey, moving with incredible precision when they strike. Every year, thousands of humans fall victim to crocodile attacks. During World War II, in Myanmar, a unit of 1,215 Japanese soldiers was wiped out by a group of hungry swamp crocodiles. Today, the saltwater crocodile is regarded as the most dangerous and aggressive predator on Earth.

In modern life, crocodiles are also farmed for their skin and meat. Their skin is used to create durable and highly valued luxury items. Crocodiles are sometimes kept for tourism or entertainment purposes, though they remain untamable and pose a significant danger to humans.

Crocodiles have been featured in various cultures. In some places, they are symbolic of the cosmos, the land, and the spirit of the unknown, yet they also represent the mystery of life. In Africa, their power is compared to that of hell, and they are associated with the forces of fire and water. In some African tribes, crocodile dances are performed in festivals that invoke the earth and the sun.

In ancient Egypt, crocodiles were seen as soul-eaters, unstoppable once they clamped down on their prey. The Egyptians believed that a crocodile god governed the rivers and needed to be worshipped. As such, crocodiles were considered sacred, and their eyes symbolized the burning sun, their mouths represented death, and their tails symbolized darkness.

In Thailand, crocodiles are revered as rulers of the waters, controlling the seasons and crops. In Cambodia, they are seen as symbols of gentle light, akin to the lightning that heralds rain, both gentle and fierce.

In Vietnam, where agriculture and water-based livelihoods are central, crocodiles have long been admired as symbols of prosperity and strength, almost divine in nature. Images of crocodiles adorn decorations and paintings. The Vietnamese people both fear and revere their power and mystery. In some cases, crocodiles symbolize darkness, cruelty, and terror.

Today, due to habitat loss and excessive hunting, crocodile numbers in the wild have greatly diminished. In the past, they were common in the rivers of the Mekong Delta in southern Vietnam and some large rivers in central Vietnam. Nowadays, wild crocodiles are rarely found. Without conservation efforts, these creatures may disappear from the wild in the future.

Squirrels are undoubtedly one of the most common and friendly animals to humans. Known for their small, cute appearance, they are found across various continents, countries, and climates.

Squirrels, classified under the scientific family Sciuridae, are small rodents easily identified by their remarkable agility. These creatures can be found worldwide, with various species including tree squirrels, flying squirrels, and ground squirrels.

Squirrels are incredibly endearing, with bodies measuring between 7 and 10 cm in length, while the larger ones can reach 15 to 18 cm. They weigh approximately 10 grams. Their fluffy tails, large eyes, and small ears are distinctive features. Their fur is soft and sleek, and their hind legs are longer than their front legs, aiding in climbing. Each foot has 4 to 5 toes, with sharp claws designed to help them grip tree trunks securely. The bushy tail not only assists with balance but also serves to shield them from the sun, rain, or cold weather. Similar to other rodents, squirrels have 4 constantly growing incisor teeth that they need to gnaw on to keep in check.

One fascinating trait of squirrels is their exceptional sense of smell, which allows them to find buried food, even under snow. They habitually store food for winter, but they do not hibernate.

Squirrels are present all over the world, with roughly 200 species identified. Some key types include:

Flying squirrels, a subgroup of marsupials originating from Australia, are named for their ability to glide through the air. By extending their arms and legs, they can soar from one tree to another, covering distances between 70 to 100 meters. They have exceptionally soft fur, a dark stripe running from head to tail, and small, pointy ears. Their bodies are equipped with a thin membrane stretching from their arms to their legs, allowing them to glide effortlessly. The tail plays an important role in stabilizing their flight. Additionally, they have a small pouch on their belly for carrying their young and storing food. These squirrels are gentle and sociable in nature.

Tree squirrels, found all over the world except Australia and Antarctica, have slender bodies and long, bushy tails. Their fur can be brown, gray, reddish, or black, with a lighter belly. Their sharp claws and thick tails make it easier for them to move through trees. These squirrels typically live in tropical forests, secondary woodlands, and other environments like terraced fields, bamboo forests, or pine woodlands.

Ground squirrels mainly reside on the ground and are known for their ability to stand on their hind legs for extended periods. They are social animals, often living in groups. They are omnivores, eating nuts, insects, eggs, and small animals. They measure around 18 cm in height and have golden-yellow fur. They can be found in meadows, fields, and rocky areas, and are generally more sociable than other squirrel species.

The mating season for squirrels typically occurs from February to May. Both males and females can mate with multiple partners. During mating, the male secretes a waxy substance that prevents other males from mating with the same female.

The gestation period for squirrels lasts between 30 and 35 days, with each litter producing 2 to 5 offspring. Newborn squirrels are blind, hairless, and toothless for the first 2 to 3 months, during which time the mother cares for them and provides food. A female squirrel can have multiple litters throughout her life.

Squirrels play a crucial role in forest regeneration by dispersing seeds. Their main diet consists of seeds, and their feces contain seeds that are scattered throughout the forest, enriching the soil and promoting plant growth.

Furthermore, squirrels store food for the winter, which helps seeds germinate in the spring, fostering the growth of various plants. This behavior significantly enhances the ecological importance of squirrels, increasing their value in nature.

The pangolin is a fascinating and beautiful creature, known for being the only mammal in the world covered with scales. Its large, long claws allow it to dig burrows underground for shelter and to excavate ant and termite nests for food, while also aerating the soil, improving its nutrient quality, and assisting in decomposition. This contributes to creating a fertile base for plant life to thrive.

Pangolins, also called scaly anteaters, belong to the mammal order Pholidota, a term derived from the ancient Greek word φολῐ́ς, meaning 'scale.' There is only one surviving family, Manidae, which includes three genera: Manis, Phataginus, and Smutsia. The Manis genus, with four species, is found in Asia, while Phataginus and Smutsia each have two species native to Sub-Saharan Africa. These species range from 30 to 100 cm in length. Some pangolin species have already gone extinct.

The pangolin’s body is covered in large keratin scales, similar to human nails, which provide protection and hardness. It is the only known mammal to have this feature. These animals live in hollow trees or burrows, depending on the species, and are found in tropical regions of Asia and Africa. Pangolins are nocturnal creatures, primarily feeding on ants and termites, which they capture using their long, sticky tongues. During the day, they curl into a ball to sleep. They are solitary animals, meeting only to mate and usually giving birth to one to three offspring, which they care for for up to two years.

The pangolin is threatened by poaching (for its meat and scales, which are used in traditional Chinese medicine) and deforestation, which heavily impacts its natural habitat. It is the most trafficked mammal in the world. As of January 2020, three pangolin species—Manis culionensis, M. pentadactyla, and M. javanica—are listed as critically endangered; three others—Phataginus tricuspis, Manis crassicaudata, and Smutsia gigantea—are considered endangered; and two species—Phataginus tetradactyla and Smutsia temminckii—are vulnerable according to the IUCN Red List of the International Union for Conservation of Nature.

The name 'pangolin' comes from the Malay word 'pengguling,' meaning 'the one who rolls up.' In modern Malay, it is known as 'tenggiling,' in Indonesian as 'trenggiling,' and in the Philippines, it is referred to as 'goling,' 'tanggiling,' or 'balintong'—all meaning the same thing.

The pangolin’s entire body is covered in overlapping scales that resemble pinecones, leaving only the belly area uncovered. At birth, pangolin scales are soft but harden as they mature. Made of keratin, like human nails and claws, their scales differ in structure and composition from those of reptiles. The sharp, pointed edges of the scales help with defense. When threatened, the pangolin can curl into a ball, with its scales stacking up like armor, protecting its face by tucking it beneath its tail. Its sharp scales provide additional defense against predators. Pangolins also have a defense mechanism similar to the skunk, releasing a foul-smelling acidic liquid from glands near their anus when threatened. Their long, hard claws are used to break into insect nests, dig tunnels, and climb. With no teeth, they primarily feed on ants and termites. They use their long, sticky tongues (which can reach up to 40 cm with a diameter of only 0.5 cm) to catch prey. Their tongues are stored in the chest cavity, between the sternum and trachea. The pangolin’s tail is also prehensile, helping it grasp branches while climbing.

Pangolins consume a variety of insects, mostly ants and termites, although they occasionally supplement their diet with other insects, especially larvae. They are known for being selective, often consuming only one or two species of insects, even when others are available. A pangolin can eat 140 to 200 grams (5 to 7 ounces) of insects per day. They play an important role in regulating termite populations in their natural habitat. Pangolins have poor eyesight and lack teeth, relying mainly on their sense of smell and hearing. Their robust skeletal structure, particularly their strong forelimbs, is essential for breaking into termite mounds. They use their strong front claws to dig into trees, the ground, and vegetation to find prey, then use their long tongue to probe inside insect tunnels and extract the food. Their tongue and stomach structure are key to their ability to locate and digest insects. Their sticky saliva causes ants and termites to adhere to the tongue as they hunt in the insects' tunnels. Despite having no teeth, pangolins swallow small stones that accumulate in their stomach, known as the 'gizzard,' which is covered in keratin spines. These spines aid in grinding and digesting their food. Some species, such as tree pangolins, use their strong tails to hang from branches and peel bark to expose insect nests inside.

Pangolins are solitary and meet only to mate. Males are typically larger than females, weighing up to 40% more. While their mating season is not strictly defined, they generally mate once a year, during the summer or fall. Instead of males searching for females, males mark their territory with urine or feces, and females come to them. If there is competition for mates, males will use their tails as weapons to fight for the opportunity to mate. Gestation lasts between 120 to 150 days, with females giving birth to one (African pangolins) to three offspring (Asian pangolins). Typically, only one offspring is born, though twins can occur. Newborn pangolins weigh between 80-450 grams. At birth, their scales are soft and white, but they harden and darken within a few days to resemble those of an adult. During the growing phase, the mother stays with her young in a burrow. The young cling to their mother's tail, and when danger arises, the mother hides them under her belly and curls into a ball. Some pangolin species remain hidden in burrows for 2-4 weeks before emerging. At one month old, the young leave the burrow and ride on their mother’s back. They stop nursing at around three months, and by the age of two, they reach maturity and are capable of reproduction.

Both African and Asian pangolins are heavily hunted for their meat. In China, pangolin meat is considered a delicacy in traditional medicine, believed to help with blood circulation and increase lactation for new mothers, which makes it highly prized. They are also used as a disinfectant and for treating fevers and skin conditions, either applied externally to wounds or ingested after being crushed. The body parts of pangolins, especially Southeast Asian species, are widely smuggled into markets in Singapore, China, South Korea, and Vietnam.

In addition to poaching, deforestation and environmental degradation have significantly reduced pangolin populations, especially the Manis gigantea species due to overhunting. Pangolins are endangered and protected by the 160/2013/ND-CP Decree. Let's unite to raise awareness and protect these precious creatures.

The elephant is an intelligent and family-oriented animal, known for its gentle nature and playful behavior, making it beloved by people. In Vietnam, the elephant is regarded as a symbol of the Central Highlands. However, the population of elephants has been significantly declining, with very few remaining today.

Elephants, scientifically named Elephant, belong to the family of herbivores. They are the only surviving species within the trunked mammal order. The elephant family includes three extant species: African savanna elephants, Asian elephants (primarily found in India and Southwest Asia), and the extinct mammoth species (the largest terrestrial mammals, which went extinct around 10,000 years ago).

Elephants are believed to have originated in Crete around 5000 BCE or possibly as late as 3000 BCE. They are found across sub-Saharan Africa, South Asia, Southeast Asia, and adapt to diverse environments like grasslands, forests, deserts, and swamps. Elephants are herbivores and tend to gather near water sources. They play a crucial role in the ecosystem, influencing the environment significantly. Other animals tend to keep their distance from elephants, though predators such as lions, tigers, hyenas, and wild dogs may target younger elephants. Elephants often form family units, where females lead and multiple families connect to communicate. Female elephants usually live in these family groups, which consist of a matriarch and her offspring or closely related females. These groups do not include males, and they operate under a matriarchal system.

Elephants are peaceful creatures that spend up to 16 hours a day foraging. Their diet varies by season and location but consists mainly of tree leaves, fruits, tree bark, and some grasses and herbs.

The elephant is the largest living land mammal. The heaviest male elephant recorded weighed 12 tons, but it was hunted down in Angola in 1974. There are also smaller species of elephants, comparable in size to calves or large pigs.

Elephants have large heads, trunks, and two tusks. Their legs are massive, supporting their enormous bodies, and the soles of their feet are protected by thick pads. Their foot pads contain elastic fibers, helping them move quietly. The tusks of elephants are essentially enlarged incisors, with the enamel thinning over time as the tusks grow. An elephant can have up to six sets of molars throughout its life, with the last set wearing out by the age of 55. Male elephants have larger tusks than females, and African elephant tusks are larger than their Asian counterparts. A pair of tusks can weigh over 200 kg. Elephants' ears are large but primarily serve to regulate body temperature through the rich network of blood vessels they contain. By flapping their ears, elephants cool themselves. The trunk, which is a highly sensitive extension of the nose, performs various tasks like drinking water, breathing, picking fruits, and even showing affection. Male elephants use their trunks for courtship, while females use it to comfort their calves.

An elephant typically sleeps only 2 to 3 hours a day. An adult elephant needs 300 kg of food and 160 liters of water daily. Elephants can detect rain from up to 150 miles away and smell water from 20 miles. An elephant's brain weighs up to 5 kg, although its sperm count is smaller than that of a mouse.

Elephant reproduction is unique. While elephants do not have a specific mating season, female elephants may join a herd when they are in estrus, though their presence in the herd is not constant. The gestation period for an elephant is 22 months, the longest of any land mammal. A newborn elephant weighs around 120 kg and is often covered in dirt, requiring its mother to clean it before it can stand. Elephants usually give birth in the spring. After birth, the calf is protected by other members of the herd until it is strong enough to stand. Like other long-lived mammals, elephants invest many years in raising their young. Adult elephants are too large to have many natural predators, but calves are vulnerable. Elephant calves nurse for up to five years, and males leave the herd around 13 years of age. Elephants grow slowly, with a lifespan of 50 to 70 years, although the oldest recorded elephant lived to be 82 years old.

Although elephants are gentle and lovable creatures, they are threatened by human activities. It would be wonderful if we all worked together to protect these majestic yet vulnerable creatures.

Monkeys are exceptionally intelligent animals, whose impressive cognitive abilities have long captured the attention of humans. They are highly cherished in Vietnam.

Monkeys and their relatives have a long-standing connection with the Vietnamese people, which is why the Vietnamese language has 11 different words to refer to them: hầu, khỉ, khởi, khẹc, khọn, tườu, nỡm, bù dù, đười ươi, vượn (Viên), and nghề. Monkeys belong to the class of mammals and the order of primates, and they can be divided into three major groups: New World monkeys, Old World monkeys, and tailless monkeys.

Globally, there are 351 species of monkeys, classified into 12 main families within the primate order. Of these, 62 species are endangered and need protection. They are commonly found in rocky mountain regions, caves, and forests, especially where fruit trees grow. Monkeys are omnivores, feeding on fruits, seeds, insects, and larvae. They have a particular fondness for bananas, and root vegetables like sweet potatoes and grains are considered delicacies. This is why they are often referred to as “tail-wielding thieves” for raiding farms. Monkeys live in social groups, which consist of multiple troops, each containing 20-30 members from various families and generations. Each group has a dominant male who oversees their activities, organizes patrols, ensures their safety, and secures food. When food is gathered, the leader receives a portion. The dominant male is typically strong and robust, and when he ages or dies, another dominant male from the group replaces him.

Monkeys are advanced creatures with body structures similar to humans. They have short, neat fur, and their arms and legs enable them to move in three ways: walking, running, and climbing. When they climb trees, their tails help them maintain balance. In addition to balance, their tails function like an extra hand, assisting them in navigating branches. In addition to their eyes, nose, ears, and mouth, monkeys possess 32 teeth and cheek pouches where they temporarily store food before chewing it and swallowing. Their long arms are adapted for climbing, and their hands are remarkably human-like, with opposable thumbs that allow them to grasp objects, pick leaves, and gather food with ease. They can even use their hands to remove thorns from their feet. Monkeys take great pride in their pink bottoms and are known to flaunt them for others to admire.

Monkeys live an average of 10 to 46 years. Female monkeys give birth every 3 to 4 years, usually to one offspring, and they also practice “family planning.” The early years of a monkey’s life are spent in the care of its parents, after which it gradually joins the social structure of its group. Each group establishes its own territory and rarely invades others.

Monkeys exhibit strong social bonds and familial love. They huddle together for warmth in cold weather, groom each other, and remove pests. When a monkey dies, the group covers its body with leaves, creating a simple grave. Mother monkeys are very affectionate toward their young, nursing them for long periods and searching for medicinal plants when they fall ill. If a baby monkey dies, the mother may carry its body for days, grieving and eventually succumbing to sorrow herself.

Monkeys have their own unique language. Their loud calls are used to threaten enemies, and they emit specific sounds depending on the situation: a “pffft” when they seek help in an attack, a growl when anxious, a victorious scream when they win a battle, and a sharp shriek to warn of approaching predators. Monkeys are highly intelligent and have an excellent memory, learning from their experiences, whether successful or not. They can also mimic complex tricks, such as pulling a cart, riding a motorcycle, cycling, walking on a tightrope, carrying a baby while grinding grain, and even acting in films.

In the field of medicine, monkeys are often used in research due to their physiological similarity to humans. They are integral to studies on pharmacology, toxicology, cancer, surgery, and vaccine development, especially for polio. Additionally, their body parts are used in traditional medicine to treat a wide variety of human illnesses. Plants named after monkeys, such as monkey fur or monkey leaf, are used for medicinal purposes. Consequently, monkeys have become highly valued in both science and medicine.

Unfortunately, monkeys are facing the threat of extinction due to illegal and indiscriminate hunting. Therefore, it is essential for us to implement effective policies to conserve and protect these remarkable creatures.

In today's uncertain world, many species are listed in the Red Book as endangered and are being preserved due to the imminent threat of extinction. Some of these creatures have even been recognized as world heritage, symbolizing a country's cultural identity. Among these, the giant panda is a prime example.

Native to China, the giant panda is recognized by UNESCO as a world heritage species. Although classified as a carnivore, it has a unique diet similar to that of omnivores, mainly consisting of bamboo, wild grasses, and other vegetation. Pandas live alone in their natural habitat, which is typically found in bamboo forests, and are solitary creatures, foraging for food independently.

Like other wild animals, pandas are territorial, and they mark their boundaries with their scent, either from their body or urine. If their territory is threatened, especially the female pandas, they will display surprising aggression. They communicate with one another using vocalizations.

Despite belonging to the bear family, pandas do not hibernate in the winter to conserve energy. Instead, they migrate to warmer areas, constructing nests in tree hollows to keep comfortable during the cold months.

Known for their solitary nature, male pandas leave once the mating season is over, leaving the female to bear and care for the cubs alone. Pandas are naturally gentle creatures, far less aggressive than other wild bears, but they will defend themselves if provoked with their sharp claws. There are two primary subspecies of giant pandas based on fur color—one has a white and black pattern, while the other is brown and beige. However, the more commonly recognized variety is the classic black-and-white panda.

Physically, pandas are large and stout, with an average height of about 150 cm and weighing around 135 kg. Their small, black ears sit on top of a round face, with dark rings around their eyes, often likened to humans with dark under-eye circles. Their noses are wet, triangular, and black, giving them a somewhat bear-like appearance.

Pandas have short, thick legs covered in dark fur, which contrasts with their creamy white bodies. Their round bellies, slightly bloated, store fat that helps to regulate their body temperature and provide them with energy. Female pandas carry their cubs for about five months, and typically give birth to one or two cubs. However, if two cubs are born, the mother will usually abandon the second one, as she cannot produce enough milk to nurse both. The newborn pandas are born white, and over time, their distinctive black fur gradually develops.

The giant panda is not only a national symbol for China but also an international icon. When people think of China, they often picture a panda. In addition to their cultural significance, pandas also play a major role in tourism, drawing vast numbers of visitors who come to witness these adorable creatures in person. Globally, the panda is also the symbol of the World Wildlife Fund (WWF), representing efforts to protect endangered species. Pandas are sometimes referred to as living fossils, having survived the threat of extinction, thanks to extensive conservation work to protect them as a world heritage species.

However, the threat to their survival remains real. Rapid industrialization and urban sprawl have led to the destruction of bamboo forests, their primary food source. Without this crucial resource, pandas cannot survive.

In conclusion, the giant panda is a powerful symbol, representing not only China but also global efforts to protect nature and endangered species. It is a source of national pride for the Chinese people and serves as a reminder of the importance of conservation for future generations.
