Female caimans build a large nest in which to lay their eggs. The nests can be more than 1.5 m (4.9 ft) wide. Female caimans lay between 10 and 50 eggs, which hatch within about six weeks. Once they have hatched, the mother caiman takes her young to a shallow pool of water, where they can learn how to hunt and swim.

There are also several extinct fossil species in the genus Caiman, possibly up to eight species. The broad-snouted caiman is a member of the caiman subfamily Caimaninae, and is one of six living species of caiman. Its relationship to the other caimans can be shown in the cladogram below, based on molecular DNA-based phylogenetic studies: [7]
