1. Howling - Red Wolf
The Red Wolf, also known as the 'Asian Wild Dog,' is known for its pack behavior, typically consisting of about 10 individuals. They are highly sociable and have a creative way of communicating - howling. This distinctive howl can travel up to 56km and helps them recognize each other.
The Gray Wolf is a social animal, often living in packs of 5-11 individuals, with 1-2 adult wolves leading the pack. In the pack, the alpha wolf holds supreme power, and other wolves must obey its commands when hunting or engaging in pack activities.
The Red Wolf is a formidable hunter, known for its ruthless and cunning pack hunting tactics. They are very aggressive, with terrifying howls that send shivers down the spine. When they close in on their prey, they kill it with incredibly vicious and peculiar attack methods, using their razor-sharp teeth to tear through the skin of their prey.


2. Scent-marking with Feces - Rhinoceros
Rhinos have very poor eyesight. That's why they always have to 'see' everything through their nose. If asked what rhinos like to smell the most, the answer is likely... the feces of their own kind. From the scent of the feces rhinos excrete, other individuals can sniff and follow the exact path they've traveled before.
Rhinos are animals with keen hearing and sense of smell but relatively poor eyesight. They can find each other by tracking the scent marks left by their kind along the way. A rhino can move very fast when stimulated. Their running speed can reach up to 30 miles per hour (50km/h). Despite traveling in large numbers, they are very agile, able to leap or change direction quickly.
They often live around water bodies and consume aquatic vegetation. These rhinos typically search for food during cooler times of the day, such as early morning or late evening, to avoid the heat of midday. When the sun is high, they often wallow or immerse themselves in water.


3. Mouth Smacking - Monkey Species
Scientists believe that human language may have appeared very early in the evolutionary process. According to Tecumseh Fitch, head of cognitive biology at the University of Vienna, the language signs of humans are marked by the mouth smacking sounds of monkey species.
Most monkey species engage in mouth smacking gestures when they encounter each other. This process, although emitting very soft sounds, is created through a series of intricate and coordinated movements involving the lips, tongue, jaw, and small u-shaped fingernail bones. The frequency of these gestures is 5 times per hour.
Monkeys are incredibly adorable creatures. Being a part of the Primate Order, their daily behaviors and gestures bear many similarities to humans. Even occasionally, monkeys hum tunes in their mouths. Whenever they want to gather their troop, they sing softly as if to say, 'Hey everyone, it's time for the party to begin, let's celebrate together!'


4. Ultrasound Communication - Tarsier
Tarsiers, also known as owl monkeys, are small, dry-nosed primates belonging to the Tarsiidae family, the only surviving family within the suborder Tarsiiformes. All extant species are found only on various islands in Southeast Asia, particularly in the Philippines, Malaysia, Indonesia, and Brunei.
Tarsiidae are diminutive creatures, with a maximum size of about 13 cm. Moreover, they possess an exceedingly rare characteristic in the animal kingdom: Despite the passage of 45 million years, Tarsiidae have never undergone any evolution or change whatsoever.
These individuals have a habit of engaging in 'chitchat,' communicating with each other using ultrasound. Specifically, they can emit ultrasound at frequencies of 70 kHz, reaching up to 90 kHz. Whenever separated from their mothers, juvenile tarsiers emit this ear-piercing sound. Additionally, during mating season, male Tarsiidae also call out similarly to summon their mates.


5. Harmonizing Melodies into Speech - Callicebus nigrifrons
Callicebus nigrifrons, a mammal species in the Pitheciidae family of the Primates order, resides in Brazil and belongs to the monkey family of the Callicebus genus. What makes this species intriguing is its ability to blend various melodies into a complete sentence understood only by its kind.


6. Democratic Voting among Bison
Bison are incredibly democratic creatures. When faced with 'big' decisions in life, such as... what's for dinner today? Bison individuals will move in any direction they please and persistently follow that path until other 'members' of the herd approve and comply.
Bison, also known as the American buffalo, are large, wild, even-toed ungulates, and the largest mammal species in the Bovidae family. Scientifically named Bison, these creatures were once the lifeline of the United States. Bearing the appearance of giant behemoths, their size is quite massive and becomes conspicuous in stature, with a height of about 1 meter but a length of up to 3 meters, weighing up to 1 ton or more per individual.


7. Naming Each Other - Whales
Whales are social animals, living in pods. Hence, they need 'names' to call each other when necessary. Depending on their habitat, whales have different tones and pronunciation styles.
Moreover, whales are known for their loud vocalizations to gather their pods. Male whales also produce loud sounds to attract mates during breeding season. This is the first time scientists have discovered a 'secret' form of communication between a mother whale and her calf.
When sensing danger, they will 'whisper' small enough for only the mother and calf to hear, as signaling too loudly may alert predators. Mother and calf whale pairs can hear each other's signals within a distance of less than 100 meters, especially in low-light environments with many dangers.

9. Stare Down Expert - Western Hooded Crow
The Western Hooded Crow defends its territory by expressing discomfort through its facial expressions. It enjoys intimidating others by staring from head to toe until the opponent retreats and leaves. The Western Hooded Crow is the only bird species with this peculiar ability because, as a matter of fact, the position of its pupil is always in the center and cannot look elsewhere.
The Western Hooded Crow, also known as the European Hooded Crow, Eurasian Hooded Crow, or simply Hooded Crow, is a bird species belonging to the genus Coloeus, formerly considered part of the Crow genus. Found throughout much of Europe, eastern Asia, and northern Africa, this bird species is virtually non-migratory, although individuals living in the northern and eastern regions will migrate southward in winter.


10. Sophisticated Eye Communication - Mantis Shrimp
Scientists believe that the eyes of mantis shrimps are more akin to satellites than humans. Specifically, this species can perceive up to 16 different colors, while humans can only see 3 colors. They can also see ultraviolet rays and polarized light. Thanks to their sharp vision, mantis shrimps often communicate and signal to each other through their eyes to avoid the prying eyes of predators.
The eyes of mantis shrimps are compound, with 6 rows of small eyes in the 'midband' area. These eyes contain 16 types of light receptors, with 12 types responsible for color recognition and four types serving as color filters. The vision of mantis shrimps is exceptional; they can see polarized light and possess hyperspectral color vision.
Their compound eyes are located on long stalks, and each eye stalk can move independently of the others. They are considered the most complex compound eyes in the entire animal kingdom. Mantis shrimps have the ability to analyze serial and parallel visual stimuli.
