The real American alligator
- Scientific name
- Alligator mississippiensis
- Japanese name
- ミシシッピーワニ(アメリカアリゲーター)
- Group
- Amphibians and reptiles
- Class
- Reptilia
- Order
- Crocodilia
- Family
- Alligatoridae
- Genus
- Alligator
A crocodilian that lives in slow-moving rivers, swamps, marshes and lakes in the southeastern United States.
Its nostrils sit on top at the end of its long, rounded snout, so it can breathe while the rest of its body stays underwater.
The female builds a nest of plants. The young call out with high-pitched sounds from inside their eggs to tell their mother it is time to open the nest.
How the American alligator lives
They mate at night in shallow water. They seize prey with sharp teeth and swallow small prey whole. They have periods of dormancy when the weather turns cold.
