Where the name “Saltwater crocodile” comes from
Its English name, saltwater crocodile, comes from its habitat in water mixed from sea and fresh water.
上野動物園A very large crocodile that lives where seawater and fresh water mix, such as river mouths, coasts, and mangrove forests.
When young it eats insects, frogs, fish, and the like; as an adult it also eats big animals such as wild boar and monkeys.
It hides in the water with its nostrils and eyes showing, then grabs animals that come to drink with its big jaws and drags them under.
How the Saltwater crocodile lives
When it gets too cold, it lies in the sun on flat rocks to warm up. Young crocodiles are thought to make short, high-pitched calls. It is thought to make a long, low growl during courtship.
