Definition
Genus Caiman refers to a group of crocodilians within the family Alligatoridae, native to Central and South America. Caimans are closely related to alligators but are generally smaller and have bony plates on their bellies. Several species exist, each adapted to different aquatic habitats. Think of 'genus Caiman' as the South American branch of the alligator family. Their presence indicates biodiversity in tropical ecosystems.
