Crocodile
Crocodiles are large, semiaquatic reptiles in the order Crocodylia, found mainly in tropical regions of Africa, Asia, Australia, and the Americas.
Crocodiles are large, semiaquatic reptiles found in tropical regions worldwide. They are carnivorous predators with powerful jaws and a long evolutionary history.
What it is
Crocodiles belong to the order Crocodylia and are closely related to alligators, caimans, and gharials. They have tough, scaled skin, strong jaws, and eyes, ears, and nostrils positioned high on the head for life in water. Living species vary greatly in size, from the dwarf crocodile to the saltwater crocodile, one of the largest living reptiles.
Where they live
Most crocodiles inhabit tropical wetlands, rivers, lakes, swamps, estuaries, and mangrove habitats across Africa, Asia, Australia, and the Americas. They are not native to Canada, but are featured in zoos and conservation education.
Why it matters
Crocodiles play an ecological role in aquatic ecosystems by helping maintain healthy waterways. Several species are threatened or endangered due to habitat loss, hunting, and conflict with humans. Their conservation is important for biodiversity.
In short
- Crocodiles are large semiaquatic reptiles with armored skin and powerful jaws.
- They are carnivorous ambush predators found in tropical regions worldwide.
- Species range from the dwarf crocodile to the massive saltwater crocodile.
- Several species are threatened; they are not native to Canada but appear in zoos.
