Crocodiles are large reptiles found in tropical regions around the world. They have long, powerful bodies, strong jaws, and sharp teeth, making them excellent hunters. These creatures are often seen basking in the sun near rivers, lakes, and swamps, where they can quickly slip into the water to catch fish and other prey. Crocodiles are known for their tough, scaly skin, which helps protect them from predators. They are also fascinating because they can hold their breath underwater for long periods. Like their relatives, alligators, they play an important role in their ecosystems by helping to control fish populations.
