There are many mysterious animals in nature, and they are often able to perform behaviors that amaze humans. But sometimes, animals show us things that we can't seem to understand with conventional logic. For example, crocodiles eat stones, or a large number of sheep hanging from trees. Today, we've collated the strange behaviors that 6 different animals do.
<h1 class="pgc-h-arrow-right" data-track="2" >1, crocodiles eat stones</h1>
If humans catch a crocodile, you may be able to find some remnants of prey in their stomachs, such as fish, birds, deer, and other animals, but interestingly, you may also find rocks in their stomachs. This is because these crocodiles sometimes deliberately swallow some rocks. They do this not because of their high nutritional value or good taste, but because of some more practical purpose. First, stones help them digest, crocodiles sometimes swallow large chunks of prey, and stones swallowed in their stomachs can help them crush and grind into chunks of food, especially those that are harder; second, stones can add weight to their bodies, making it easier for them to stay underwater.

Manatees were once thought to have inspired the mermaid myth thanks to their graceful swimming posture. However, this elegant creature can also perform some strange behaviors, such as farting. An adult manatee can weigh around 600 kilograms and can eat about 60 kilograms of vegetation a day, which means it will produce large amounts of methane, and the gas will be stored in storage bags in the intestine. Their ability to control these gases is quite good. Interestingly, when they release a steady gas, it can be used to help them swim. The gas stored in the intestinal pocket helps maintain the buoyancy of the animal. When manatees want to float to the surface, they control not to release gas, but when they want to sink into the water, they release gas, which makes the buoyancy less. The ability to fart is essential for the survival and health of these marine mammals.
<h1 class="pgc-h-arrow-right" data-track="6" >3, crows remember human faces and take revenge on humans</h1>
Crows are hated by many people, and even many people think that they are ugly and stupid. The reality is the opposite, the crow is one of the most intelligent animals in the world. Many people have heard the story of the crow drinking water, and the crow picked up the stone and threw it into the cup in order to drink the water. While this may sound like just a children's story, real crows can really do it because they have the ability to make and use tools. What is even more incredible is that the crow can also remember the face of a person, and it will also remember revenge and attack the humans who have hurt it. There was once a man in the United States who attacked a crow and was attacked by the same crow every day. Scientists have concluded that crows have reasoning abilities equivalent to the average 7-year-old human child. And it all has to do with its unique brain, unlike other birds, the crow has an oversized forebrain, which makes up 80% of the crow's total brain, which can help them solve problems better.
<h1 class="pgc-h-arrow-right" data-track="8" >4, drum shrimp can make a loud noise</h1>
The drum shrimp doesn't look big, only about 3.8 centimeters long, but this inconspicuous-looking critter hides a deadly weapon. It has huge pliers on one side capable of shutting down quickly at an astonishing speed of about 97 kilometers per hour. When it does, it produces a sound that can reach a deafening 218 decibels, louder than most gunshots. As they do so, the powerful water pulses they generate can stun nearby prey.
<h1 class="pgc-h-arrow-right" data-track="10" >5, capybara eats its own poop</h1>
Capybara is the largest rodent in the world, a semi-aquatic animal that can grow up to 1 meter and weigh even about 65 kilograms. They love to eat fruits, grasses and vegetables, but incredibly, they also eat their own poop. This is because the grass they swallow into the stomach is usually difficult to digest because they make it easier to carry out a second digestion efficiently by eating the excrement.
<h1 class="pgc-h-arrow-right" data-track="12" >6, goats hanging from trees</h1>
In nature, several subspecies of goats have a fairly powerful ability because their way of life looks like they are constantly challenging the laws of gravity. They have an incredible and insane climbing ability to climb extremely steep cliffs because of their excellent sense of balance, which can disperse their weight in crevices in the rocks, and they evolved this way of survival to facilitate their feeding on moss that grows in dangerous areas. In addition to climbing the cliffs, they are able to climb to the top of the trees to find delicious fruits and leaves, giving a wonderful scene of trees full of goats. In Algeria, there have even been cases where a large number of goats climb a tree with a total height of 7.6 meters.
