Crocodiles eat stones
The stomach of a crocodile – is stone place for several reasons. To begin with, everything from turtles, fish and birds to giraffes, buffaloes, lions and even other crocodiles runs through his digestive system. And stones too. Crocodile swallows them and they stay in his stomach. Presumably it is done for ballast during diving.
Whale milk – 50% fat
Taking care of the baby -is not an easy task for the whale, whose calf reaches 1/3 of the length of the mother. It has 50% milk fat content, which is about 10 times greater than the human’s milk. This allows the calf to gain weight quickly.
The birds are able to use reference points
Can you imagine traveling without noisy crowds, stubborn drivers or map? Of course not, you’re not a bird. Pigeons can fly without problems thousands of kilometers to their former place of nesting. Some species of birds use the built-ferromagnet mechanisms for orientation. In November 2006, an article suggesting that pigeons also use familiar landmarks on the ground was published. These reference points allow the birds to find their way home.
Winter days are longer for beavers
Beavers become almost hermits during winter, living off of harvested food or fat in their tails. They conserve energy by avoiding the cold by staying in their burrows. As a result, these rodents don’t have a light guide. Their biological clocks are shifted and they have for 5 more hours in a day.

The mole rats, in fact are not blind
With his weak eyes and underground lifestyle, African mole rats were considered rodents, which almost do not see the light and use their eyes to detect changes in air currents. But subsequent research has shown that mole rats still have some vision. The appearance of light may indicate that the tunnel climbed predator. Therefore, these diggers have a vision.
The chicks have altruism
It is a mistake to assume that as a result of evolution there are only selfish animals who are fighting for their own survival. In some cases, they still show altruism. Chicks have a sense of kinship. While feeding they emit a particular tweeting. This sound indicates other kinship chicks that there are food.
Many fish change their sex organs
There are so many strange land animals, it’s easy to forget about what’s really unusual is happening under the water. The strange practice of hermaphroditism is more common among fishes than among any other group of vertebrates. Some fish change sex due to hormonal cycle or environmental changes. Others simultaneously possess both male and female sexual organs.
The giraffes have unique bloodstream
Giraffe whose head is located at a height of 4 m above the ground, uses its long neck to compete for foliage with other herbivores. But with this growth there are some difficulties. The heart must pump blood 2 times stronger than cow’s blood to reach the brain, and complex vascular system should obstruct the flow of blood to the head, if it goes down.
The elephants are intelligent
Elephants have the largest brain. Do they use their gray matter at full power? It is difficult to measure the intelligence of a human or animal, but the elephant encephalization factor – is 1.88 (a person – 7.33, chimpanzees – 2.45 and a pig – 0.27). Intelligence and memory go hand in hand, assuming that the memory of an elephant’s good enough.
Parrots understand information
Parrot’s speech is generally perceived as a meaningless tweeting of feathered voice recorder. But research conducted over the past 30 years shows that parrots are capable of more than just imitation. Our feathered friend can solve some linguistic problems at the level of 4-6-year-old child. Parrots understand the meaning of “same” and “different”, “large” and “small”, as well as numbers. In addition, they can variously combine words and phrases.
