The world of our little brothers is so fascinating and diverse. It’s always interesting to learn something new about them, their habits, lifestyle and behavioral characteristics. Let's take a look at the most interesting facts about animals that will add to your knowledge base.
1. Scientists have confirmed that crows understand what death is and are afraid of it
Crows avoid places where many crows have died. When a raven dies, its relatives fly in to examine it to find out how it died and avoid a similar fate. These birds are really afraid of death and always try to avoid it.
2. Some species of tarantulas allow tiny frogs to live in their burrows.
There is a benefit for both here: the frogs are safe under the protection of the tarantula, and in return they eat small pests.
3. In the normal state, sloths' paws are clenched - and to unclench them, the sloth requires significant effort
That's why they don't fall from trees in their sleep.
4. Dogs can make judgments about people based on how they treat their owners.
In a study conducted in Japan, dog owners asked people to help open a container. There were three options for the development of events: the first helped him, the second did nothing in response to the request, the third refused and turned away. Then the people the owner turned to for help offered the dogs food. The dogs were much less likely to accept food from people who refused to help their owner, and much more willing to accept food from those who were neutral or helpful.
5. The Greenland shark reaches sexual maturity at 150 years and lives 300-500 years
6. Some squids have a toroid-shaped brain (a circle with a hole in the middle) and an esophagus running through it. If they eat something too big they could get brain damage
7. African cheetahs are so genetically similar that their organs can be freely transplanted between individuals within the species without fear of rejection
8. It is difficult to raise ostriches on some farms because they are more sexually attracted to people than other ostriches.
9. Male scorpion flies bring food to females to impress them.
However, some scorpion flies are not very good at hunting. Therefore, some males imitate females and wait for other males to bring them “gifts”. They then take the gift, fly away and give it to the real female.
10. Green sea turtle can swim faster than Usain Bolt can run
Turtles of this species are capable of swimming at speeds of up to 35 km per hour.
11. Coral is an animal related to the jellyfish. Large concentrations of corals form coral reefs and even coral islands
The world's largest coral reef, the Great Barrier Reef, stretches over 2,600 kilometers.
12. Scientists have noticed that fish use “tools” and cooperate to hunt
For example, they may deliberately hit a clam's shell with a rock so that it opens up so that it can be eaten. Some fish (eels and groupers) cooperate to hunt, communicating using special signals and using their individual advantages: eels drive prey from crevices to where the groupers are waiting for it.
13. A bear can outrun a horse over short distances. Bears are capable of developing great speed, but they are not so hardy and quickly run out of steam.
14. In some stores, gerbil mice are only sold in pairs because they feel sad being alone.
15. Snails can sleep for up to three years
16. Naked mole rats feel no pain, can live 30 minutes without oxygen, don't get cancer, and can live 30 years
17. Thanks to squirrels, thousands of new trees grow every year. This is because they forget where they hid their nuts, acorns and other supplies.
18. Initially, the web is a liquid protein mass produced by special glands. When exposed to air, the web hardens, forming a substance that is 5 times stronger than steel.
It is believed that if a spider could produce webs as thick as a pencil, they would be strong enough to stop an airplane in flight.
19. A parasite lives in fresh water, which first “settles” in the brain of a fish, and then, when the fish is eaten, for example, by a bird, it moves to it
20. A narwhal's horn is actually an overgrown fang. Some narwhals may have 2 "horns"
21. The height of ancient penguins could reach 2 meters
22. Seals get seasick if you put them on a boat.
23. Polar bears accumulate so much vitamin A that eating their liver can cause death. One polar bear liver contains enough vitamin A to kill 52 adults.
24. Avocados were once bred to be eaten by giant ancient sloths - they helped spread seeds efficiently
The sloths ate the fruit with the seed inside, the seed passed through the gastrointestinal tract and was excreted somewhere else, where new avocados then grew. The seed excreted along with feces received excellent fertilizer. At that time, avocados had even larger seeds than they do now.
25. Unlike their monogamous relatives, deer hamsters often have orgies, and females give birth to babies from more than one partner
26. Giraffes have the same number of cervical vertebrae as humans
27. Armadillos are the only animals that can spread leprosy (like humans)
28. There are not many bees in Australia, so plants are often pollinated by birds.
29. Porcupine quills have an antibiotic effect - so if he gets injured (even by his own quills, for example, when falling from a tree), he can easily avoid infection
30. Scientists thought the platypus was a fictional animal until they sent a dead platypus for research.
