The Nile crocodile is a large reptile found in various freshwater habitats across Africa, including rivers, lakes, and swamps. It is known for its powerful jaws and strong body, which can reach lengths of up to 16 feet (5 meters). This species is a top predator, primarily feeding on fish, birds, and mammals. Nile crocodiles are cold-blooded and rely on their environment to regulate their body temperature. They are also known for their social behavior, often seen basking in groups. Their skin is covered in tough, scaly armor, providing protection from predators and environmental elements.
