Caiman is a genus of reptile in the Alligatoridae family. They are found in Central and South America, and differ from the alligator by the absence of a bony septum between the nostrils, and the ventral armour is composed of overlapping bony scutes, each of which is formed of two parts united by a suture. Caimans tend to be more agile and crocodile-like in their movements, and have longer, sharper teeth than alligators. Although the Caiman has not been studied in-depth, scientists have learned that their mating cycles (previously thought to be spontaneous or year-round) are linked to the rainfall cycles and the river levels, which increases chances of survival for their offspring.

Species

The genus contains three extant species, two extant subspecies and two extinct species:

* Yacare Caiman, Caiman yacare
* Spectacled Caiman, Caiman crocodilus
o Rio Apaporis Caiman, C. c. apaporiensis
o Brown Caiman, C. c. fuscus
* Caiman lutescens (fossil)
* Caiman sorontans[citation needed] (fossil) - Not reported in the literature, probably a 'nomen nudum'
* Broad-snouted Caiman, Caiman latirostris
