24 Facts About the Animal World We Should Have Studied in Biology Class
We share the planet with billions of other creatures that are extremely different from one another. Every single species has its own unique features that are really impressive. For example, did you know that hippos have red sweat, that bearcats smell like popcorn, and that some antelopes eat birds?
We at Bright Side would love for you to read these short facts about animals, birds, and other creatures. They are fun, confusing, and surprising all at the same time!
1. Polar bears have black skin and colorless fur, so it doesn’t get gray with age. Only their claws do.
2. Male llamas bite off other male llamas’ testicles to get rid of competitors during the mating season
3. If a snake looks like a sausage and its eyelids don’t move, it is not a snake, but a harmless, legless lizard.
4. There are worms that eat rocks.
5. Newborn pandas don’t have black spots, they appear later. Just like Dalmatian puppies.
6. In order to protect themselves from the sun, hippos have red sweat that looks like blood. And dwarf hippos have pink sweat.
8. Tigers love to swim and lions don’t. This is genetic. So, ligers can also easily swim and tigons only do it when necessary.
9. Possums eat dozens of venomous snakes, thousands of ticks, and rarely get infected with rabies because their blood is too cold.
10. Crayfish eat their own shells in order to restore their calcium balance after shedding it.
11. Hatchlings of crested coua birds have special markings inside their mouths to let the parents know where to put the food.

15. The needles of a porcupine are only safe for the first 30 minutes of its life until they become stronger.
16. The protective shells of a baby pangolin are too soft, so in the beginning of its life, it sits on its mother’s belly. In dangerous situations, the mother curls protecting both herself and the baby.
17. Elephants have hair, not to keep them warm, but to cool them down: it reflects the heat from their skin and helps to hold on to the cold sand elephants lie in when it’s hot.
18. Raccoons have very sensitive receptors on their paws, and the sensitivity increases in water. Thanks to these, raccoons can just touch something to know what it is and they can climb on almost any surface
19. A bear cub weighs only 500 grams. When it grows up, its weight is 1,000 times bigger.
20. During mating season, deer don’t just fight with their competitors but also wear crowns of twigs and bracken to attract females.
21. Quokkas swallow and digest food, then vomit it up and eat it again to get the nutrients we get from meat.

23. Stingrays never see what they eat: their mouth is on one side and their eyes are on the other. But their sense of smell is much better than their vision.
