#18. Animal Facts: Koalas have unique fingerprints

The paw print of a koala mimics a human fingerprint. Indeed, in Australia, where the koala lives, the police fear that the koala may contaminate the crime scene, so the criminal is released. They have claws on their front and back feet. The claws on their hind feet are unique because the second and third digits are fused, and they use them to care for themselves. This is if they are awake because koalas sleep for up to 20 hours a day.

#17. Animal Facts: Some sharks glow in the dark

There are at least 15 species of deep-sea sharks that produce light with special cells on their stomachs. These sharks live in the depths of the ocean with the most sunlight ever. Marine biologists hypothesize that sharks use the fearsome green light to hide from other marine animals swimming beneath them. Kitefin, which can reach 6 feet in length, is the world’s tallest light-producing animal, called a bioluminescent vertebrate. However, scientists know that some species of giant squid also produce their own light.

#16. Animal Facts: The slow loris is the only poisonous primate

There are more than 200,000 poisonous animals in the world. However, the only member of the primate family is the slow loris. Only five species of mammals in the world are poisonous, but the slow loris is unique in that it often bites other slow lorises. In order to produce poison, this boss raises his arms before licking the bottom of his upper arm. The poison, which contains the same compound found in cat dander and other substances, causes skin to rot. Scientists believe that the most common reason slow lorises use their venom is to protect their territories.

#15th. Animal Facts: Chimpanzees love to get drunk

In Guinea and West Africa, people peck the raffia palm and collect the sap that has an alcoholic content of between 3.1% and 6.9% by volume. While the locals love to drink the sap, so do the chimpanzees. They will use a leaf as a cup to drink the fermented sap. It turns out that guinea chimpanzees aren’t the only ones who like a drink. Slow lorises like to drink alcohol from the pratam palm, which contains about 3.8% alcohol by volume. Meanwhile, green vervet monkeys love to steal cocktails from tourists in St. Kitts.

#14. Animal Facts: Wood frogs freeze themselves

Wood frogs have a unique way of surviving when they are freezing outside. Nuclear proteins in the frog’s blood cause the water to freeze in the frog’s body. At the same time, the frog’s liver produces large amounts of glucose, which supports the cells of reptiles. This process dries out the frog’s body so that it can remain hidden under a sheet when the weather cools off. Brain and heart activity stops. Then, when the weather warms up, the water slowly returns to the frog’s bloodstream. After that, its organs begin to function again, and the frog resumes its jumping.

#13. Animal Facts: Some turtles get oxygen through their buttocks

Like the eastern painted turtle and the Australian Fitzroy river turtle, some species of turtle take in oxygen and release carbon dioxide through their nape when the weather turns cold. These turtles hibernate for up to 5 months. While hibernating, they use blood vessel-lined sacs near their cloaca to take in oxygen and exhale carbon dioxide. The blood vessels then disperse the oxygen throughout the turtle’s body while collecting carbon dioxide to expel it.

No. 12. Animal Facts: Queen mole rats render other female moles sterile

Mole rats live in colonies with one queen, which is lighter in color than all other mole rats who serve as their servants. In order to ensure that they are the only mole rats to give birth, they excrete a substance in their urine that makes all other mole rats sterile. When a queen dies, there are brutal battles that often end in death to determine the new queen. About six months after the new queen was identified, she began excreting the substance in her urine.

No. 11. Animal Facts: Horned lizards spew blood from their eyes

Horned toes have two constricting muscles that line the important veins around the eyes. When a horned lizard feels threatened, these muscles contract, preventing blood from flowing back into the animal’s heart. Then, if the lizard still feels threatened, it contracts its muscles even more, causing blood to flow out of the lizard’s eyes.

#10. Animal Facts: Elephants have a specific human danger call

It is a well-known fact that elephants have specific sounds they make to communicate with each other. Researchers in  Kenya  played a recording near relaxing elephants of people speaking the local language. The elephants repeatedly made a low roar, and either became agitated or turned away. Next, the researchers created a recording of the low rumbling sound and played it to a different group of relaxed elephants. Immediately they became anxious and moved away from the area, even though there were no humans around. The rumble sounds very similar to the call that African elephants make when bees are near human ears. However, with the clatter of bees, the elephants shake their heads violently while no head shaking is observed with the human bang.

#9. Animal Facts: Dogs smell the passage of time

Dogs can predict when you will come home as long as it is expected, such as going to work or home every day. When you leave the house, you smell strong at home. Over time, your scent begins to fade. According to researcher  Alexandria Horowitz  , dogs can tell when it’s time to return to the amount of smell left in the home.

#8. Animal Facts: Reindeer’s eyes change colors according to the season

A glossy, reflective layer behind the retina in reindeer eyes that changes colors based on the season. When summer comes, the layer, called tapetum lucidum, is golden, but with the onset of winter, it turns blue. It’s the same part that causes the eyes of many animals to glow. Scientists believe that it turns blue in the winter to take advantage of any available light because they often live in areas where there is no sunlight in the winter.

#7 Animal Facts: Dolphins get high on puffer fish

According to Smithsonian Magazine, dolphins gently play with the puffer fish to be stabbed, causing the puffer fish to release a toxin. In small enough quantities, this substance puts dolphins into a drug-induced trance.

#6 Animal Facts: Flamingos can only eat with their heads upside down

Flamingos must turn their head upside down to eat because their mouth acts like a large sieve. Therefore, they need to capture food in comb-like extensions on its beak using its tongue.

#5. Animal Facts: A female ferret dies if she is exposed to heat and cannot find a mate

The female ferret reaches sexual maturity during her first spring. If a ferret goes into heat and cannot find a mate, it will eventually die of aplastic anemia, as the body stops producing new blood cells. This can lead to a prolonged painful death from infections.

#4 Animal Facts: Penguins make a wave of a thousand animals

Weather conditions, such as 200 mph winds and -58 degrees weather, make it difficult for emperor penguins to survive the Antarctic winter. Therefore, they congregate together in groups of up to 1,000 birds so that they can rely on each other’s body warmth to survive. When one penguin moves less than 0.8 inches, the entire group moves the same amount to keep it huddled together. This little movement usually happens every 6 to 12 seconds.

#3 Animal Facts: Working fire ants take 250 energy naps a day

Researchers have discovered that worker fire ants take up to 250 naps per day. Each nap only takes about a minute. About 20% of the colony is asleep all the time. By comparison, the queens slept about 90 times a day for an average of 6 minutes.

#2. Animal Facts: Polar bears have black skin

Polar bears have black skin to help them absorb as much heat as possible. Their fur is not white but consists of hollow translucent tubes of keratin. These tubes scatter the light so that we can see that most polar bears are white. Each tube helps the light pass close to the bear’s skin, where it can use it to stay warm.

#1. Animal Facts: A baby kangaroo is the size of a grape

When a baby kangaroo, called Joy, is born, it is about the size of a grape. It travels unaided through its mother’s fur until it reaches her pouch, where it will remain for the next 10 months. He is so weak that he cannot breastfeed, so the mother pumps milk into his throat.
