Appearance

The black caiman has a bony ridge over red eyes, and black, scaly skin. The skin coloration helps with camouflage during its nocturnal hunts, but may also help absorb heat (See thermoregulation

In Fiction

They were also mentioned in Matthew Reilly's best selling book "Temple", where they are constantly eating people that fall in the water. As well, it was featured rather prominantly in "Amazonia" by James Rollins wherein a Special forces soldier is eaten by a Black Caiman after it capsizes the inflatable boat in which he is riding.

Reproduction

In December, females build a nest of soil and vegetation, which is about 1.5 meters (5 ft) across and 0.75 meters wide (2.5 ft). They lay from 50 to 60 eggs

, which hatch in about six weeks. They sometimes eat their young. It has been shown that these animals frequently remove their young from the nest,in their mouths [thus the belief of some, they eat their young] at hatching, and transport them to a 'holding pool' area. The mother will even assist hatchlings to break out of their eggs,[they 'squeak' inside the egg, which the mother hears] which are tough and leathery, by chewing the egg to break it open for the young to emerge. The mother will look after her young for several months. The female black caiman only breeds once every 2 to 3 years.
