The Fennec Fox, also known as the desert fox, is a nocturnal animal that measures around 40cm, including its tail. With a lifespan of up to 14 years, it has a cream-colored coat that helps protect it from the daytime heat and keeps it warm at night. Its large, long ears aid in heat dissipation and cooling its body, making them one of its most distinctive features.
The Fennec Fox is a small, highly adaptable animal that thrives in high-temperature desert environments. It has exceptional hearing, enabling it to detect prey moving underground. The fox typically digs deep burrows in the sand for shelter and to escape predators. Its diet consists mainly of insects, small birds, and other mammals. Energetic and playful, the Fennec Fox is well-suited to its desert habitat, particularly the Sahara Desert. Its average lifespan ranges from 12 to 16 years.


7. Mandarin Fish
The Mandarin Fish is a saltwater species, typically characterized by its blue color. Male fish are generally larger and more vibrant than females. Known as one of the most beautiful fish in the world, they are found in the Pacific Ocean.
The Mandarin Fish is often found near coral reefs, where it tends to stay hidden during the day and only emerges at night to find a mate. Its diet consists mostly of small crustaceans and invertebrates. This fish is also a popular choice for aquarium enthusiasts, despite being expensive and difficult to care for. However, their stunning appearance makes them a worthwhile addition to any aquarium.
The name Mandarin Fish is derived from its striking colors and patterns, which resemble the traditional robes worn by scholars (called 'Trạng Nguyên') during ceremonial events. This connection inspired the Vietnamese to name the fish after the scholar rank, highlighting its beauty and distinction.


8. Sunset Moth - Madagascar
The Sunset Moth of Madagascar is a species of nocturnal moth in the Uraniidae family. It is considered one of the most striking and fascinating Lepidoptera species. Famous worldwide, the Sunset Moth appears in numerous insect collections and is highly sought after by butterfly enthusiasts. Initially thought to originate from China or Bengal, it was later identified as native to Madagascar.
The Sunset Moth has a wingspan ranging from 6 to 9 cm and boasts an incredibly vivid array of colors, including shades of blue, green, yellow-orange, red, purple, black, and white. These colors are not pigments but are produced through light diffraction and the unique texture of their wings, which means their hues change depending on the angle of view, environment, and time of day.
The Sunset Moth can be found year-round across the island, with the highest numbers seen between March and August and fewer during October to December. Females lay about 80 eggs on leaves.


9. Tiger
The Tiger, scientifically known as Panthera tigris, is the largest member of the cat family (Felidae). Commonly referred to as 'cọp', 'hùm', or 'chúa sơn lâm' in local dialects, tigers are native to Asia, primarily found in India, Southeast Asia, and Siberia. In Vietnam, their population is declining, with a few remaining in remote forest areas along the Vietnam-Laos border, Nghệ An, and Lâm Đồng.
Tigers are large animals that typically inhabit dense forests or vast grasslands, which provide ideal conditions for stalking prey while offering camouflage. A tiger can weigh between 150 to 310 kg and reach lengths of up to 3.3 meters, capable of moving swiftly. Their coat comes in a variety of colors, including yellow, red, orange, and white. Some tiger variations, such as white tigers, golden tigers, black tigers, and gray tigers, have been recorded. These varied colors help them blend into their harsh natural surroundings.
Tigers are solitary animals, coming together only during mating season. Male tigers tend to be more promiscuous, while females are known for being selective and loyal when choosing a mate. Female tigers generally reach sexual maturity around years, while males mature a bit later.


10. Poison Dart Frog
The Poison Dart Frog, scientifically known as Dendrobatidae, is native to Central and South America. Despite their small size, around 5 cm, these frogs are incredibly deceptive due to their vivid colors and can carry a potent toxin. This toxin can disrupt nerve cell activity, paralyze muscles, and even lead to death. The venom of a single golden poison dart frog can kill nearly 20 healthy adult humans or even two African elephants. The indigenous people have used this toxin as a deadly weapon, and scientists are also studying it for potential pain-relieving drugs.
The Poison Dart Frog displays vibrant colors like yellow and green, often with striking patterns, which serve as a warning to predators. Despite their deadly toxicity, these frogs are facing the threat of extinction due to habitat destruction caused by deforestation.
