Crocodiles are large reptiles that live in rivers, lakes, and swamps. They have long bodies, powerful tails, and sharp teeth, which help them catch fish and other animals. These creatures are known for their tough, scaly skin and can often be seen basking in the sun. Crocodiles are cold-blooded, meaning they rely on the sun to regulate their body temperature. These fascinating animals are part of the Crocodylia order, which also includes alligators and caimans. Crocodiles are excellent swimmers and can hold their breath underwater for long periods. They play an important role in their ecosystems by helping to control fish populations and maintain the health of their habitats.
