caiman

This term refers specifically to New World crocodilians, distinguishing them from the true crocodiles of Africa and Asia. The primary distinction lies in the snout shape and the way the teeth fit together when the jaw is closed, creating a more blunt appearance compared to the pointed profile of a crocodile.

In a biological context, the word evokes images of freshwater swamps and riverine habitats in the Americas. It is used primarily in zoological, ecological, or travel contexts and carries a neutral, descriptive connotation rather than the predatory dread often associated with the word alligator.
