The cold-blooded egg-laying reptile can describe the crocodile. The crocodile is not a fish. Perhaps because it can play in the water like a fish, it is named "crocodile". The crocodile is an animal from the same era as the dinosaurs. The dinosaurs are extinct, but the crocodile is still alive, which shows that it has a tenacious life. Now let's learn about this large carnivore crocodile.
Because the crocodile is an animal of the same era as the dinosaurs, it has a high status in the history of biological evolution. In people's eyes, "evil fish" is used to describe them more vividly, because when talking about crocodiles, they immediately think of their big mouths, full of sharp teeth, and their whole bodies are covered with hard armor. It looks like it is preparing to catch prey with its mouth wide open, so it is more appropriate to call it "evil fish".
Crocodiles love to eat as long as they have meat. In many prairie lake areas, there are always some crocodiles living in them. They lurk in the water and wait until the animals on the prairie go to the lake. You will be attacked by them when you drink water, and most of the animals attacked by them become a feast in their mouths.
When crocodiles reach the breeding season, they will use their tails to sweep out a platform of seven or eight meters on the river. There is a three-meter-diameter nest for placing crocodile eggs on the platform. The nest is 3 meters away from the river. About four meters, there are many leaves forming a shade. There are about fifty crocodile eggs in each nest. The female crocodile will wait beside the nest and often wet the nest with water to maintain the temperature inside the nest. Crocodile eggs use heat to incubate. The sex of the young crocodiles is completely determined by the temperature inside the nest, but the female crocodile will balance the sex ratio, so the places where the nests are built vary.
Because the whole body of crocodiles has high medicinal value, many hunters hunt them on a large scale and resell them after hunting. Therefore, many types of crocodiles are now on the verge of extinction, and many species of crocodiles have been listed Protect species. We all must also take action to join the ranks of protecting crocodiles.
