Crocodilians are ancient reptiles that have thrived for millions of years. They are semi-aquatic predators found in tropical and subtropical regions. The three main families are crocodiles, alligators, and gharials, each with distinct features. Crocodilians are adapted for aquatic life with specialized bodies for swimming and hunting. They have unique locomotion methods on land, including low and high walks, and can leap using their hind legs and tail.
