Interesting stories about animals

Unborn crocodiles have what? Pigeons find their way home how? Can parrots understand the voice of people? . Please discover interesting stories about terrestrial and aquatic animals.

The stomach of crocodiles is always lumpy , because they swallow everything from turtles, fish, birds to giraffes, buffaloes, lions and even other crocodiles. Due to such a situation, the gravel also appears in the crocodile's belly. They swallow big stones and sometimes lie permanently in the abdomen. These stones can also be used as ballast for diving.

Raising a baby is not a small affair with whales , when their offspring, after 10-12 months in the womb, will be as big as a third of their mother's length (9 m with a tiny blue whale) . The mother sprayed milk into the baby's mouth with muscles around the mammary gland while the baby hugged the mother's neck tightly. With nearly 50% of the fat, whale milk has 10 times the fat content of human milk, helping the young to achieve rapid growth, nearly 9 kg per day.

Doves can fly thousands of kilometers to find the right place without any difficulty. Some birds, like Antarctic terns, make a round trip of 40,233 km per year. Many species use in-person magnets to find the direction corresponding to the earth's magnetic field. A 2006 study also found pigeons using ground markers to help them find their way home.

Beavers are almost non-active in the winter , they only live on pre-stored food or fat in the large tail. Beaver maintains energy by avoiding cold weather, they would rather stay in dark caves. As a result, these rodents have no concept of time and they develop a free cycle of 29 hours a day.

With eyes and life underground, the African mole has long been considered almost blind, eyes only to feel the air, not to look. But a new study found that mole rats are actually still visible, and they just don't like what they see. Seeing light means that a predator has broken into the tunnel.

It is wrong to think that evolution creates selfish animals that only care for their own survival. Altruism occurs in cases where it can help preserve similar genes to you.Young birds help each other by making a special cry when eaten . This call is to inform you that you are looking for food for even your neighbors who are close relatives and share many genes with you. The key to natural selection is not to create the best healthy animals, but the best genome, so behaviors that favor close relationships will always develop.

Bisexual status occurs in more fish species than any vertebrate animal. Some fish change sex to adapt to climate change. Other animals also possess both male and female sex organs.

The giraffes have a tall neck to scramble for leaves with other plant-eating species . Although the height advantage is obvious, they still encounter some other disadvantages. The heart must operate twice as much as the cow to bring blood to the brain and need a complex blood vessel system to make sure the blood does not rush to the face as the head is lowered. At the bottom, the skin of the feet must also be extremely strong to prevent blood from remaining in the abdomen.

Parrot's words are often said to be meaningless mimics. But research over the past 30 years shows that parrots don't just mimic humans . They can handle language like a 4-6 year old child. They can understand the meaning of words like "different", "different", "bigger", "bigger" and numbers. What's more interesting is that they can incorporate phrases in a very creative way.

Elephants have the largest brain among animals walking around the earth - nearly 5 kg , but do they use them all? The intelligence is difficult to quantify in humans and animals, but the EQ ( encephalization quotient ), the ratio of the size of the animal's brain to the size of the brain is needed on the total body mass, having a similar relationship corresponds to the ability to handle challenges and obstacles. The average EQ in elephants is 1.88. In humans, 7.33 - 7.69, and chimpanzees are 2.45, pigs 0.27.
