Crocodiles (crocodile; crocodiline suburbs, known as their tru crocodile) are a type of hybrid animal. They can be seen in Africa, Asia, North America and South America and on the continent of Australia.
All types of crocodiles are similar in shape and biology. But their size, nature, behavior and habitat are different according to species. However, there are a number of similarities between them. All crocodiles are semi-submissive animals. They mainly live in the sweet water of rivers, lakes and wetlands. Some species of crocodiles also live in semi-saline and salt water. They are carnivores. Mainly fish, reptiles, birds and mammals are their food.
Crocodiles live in the equatorial region. They are sensitive to cooler environment. About 50 million years ago, they were separated from other Crocodilians in the Eocene era. Like other branches of the Crocodilomorphiera, this branch has survived despite the mass extinction for the last two and a half million years. But now there are many species of crocodiles endangered or extinct due to habitat problems and illegal hunting.
