The family Crocodylidae, belonging to the order Crocodylia, comprises the true crocodiles, large semiaquatic reptiles found in tropical regions of Africa, Asia, the Americas, and Australia. Crocodylids are characterized by their elongated bodies, powerful tails, armored skin with bony scutes, and long snouts filled with conical teeth designed for grasping and holding prey. They are primarily carnivorous, feeding on fish, birds, and mammals, and are skilled ambush predators both in water and along shorelines. Most species inhabit rivers, lakes, and wetlands, and many exhibit complex social behaviors, including territoriality and parental care of eggs and hatchlings. As apex predators, crocodiles play an essential role in maintaining the balance of their ecosystems.
