Whether we talk about home or wildlife, animals and their world have always been a mystery to us.

There are so many things that we do not know and have not yet learned about the wonder and mystery world of animals. Even if we have them in our home or admire them in their natural environment, the animals have always been an enigma and have been able to amaze us very often with their personality and special peculiarities.

1. The chameleon's tongue can reach the double length of its body.

2. The polar bear's coat is white because the middle of the fur coat is empty, and through it reflects more light than in snow and ice. The skin of a polar bear is black.

3. Elephant does not see very well, but it is helped by ears and nose. May smell the water 4 km away and is the only animal that can not jump.

4. Tigers have not only stripes on their fur but also on their skin and there are not two tigers that have the same stripes on the body.

5. A useful tip for those who want to go into a more dangerous adventure: To get rid of a crocodile, push with his thumb in his eyeball. It will let you go instantly. Moreover, crocodiles can not take off the tongue because they have a protection against biting it because of strong jaws.

6. Female feral can die if it does not mate. During the heat, their body secretes a very high level of estrogen, and if the hormone stays in the blood for too long, it can cause an aplastic anemia of the bone marrow that is fatal.

7. Among other animal curiosities is this: the nose of each cat is different, so they can be identified according to this trait, in the same way that people are identified by fingerprints.

8. The chimps chew up as they age, just like humans.

9. Dolphins always sleep with an open eye. They produce different sounds by calling the other members of the group. Biologists have likened this process to the one by which people shout among themselves.
