Spectacled Caiman Caiman crocodilus

The Spectacled Caiman, also called Common Caiman, is native to much of Central and northern South America. The name "spectacled" is said to relate to the bony ridge behind the eye resembling a pair of spectacles, but: - several other crocodilians have this feature (many crocodiles and the alligator) and - whoever named this needs to see an optician.

Caimans are generally smaller than crocodiles. The Spectacled Caiman can reach lengths of some 2 metres (just over 6 feet).

Its usual habitat is freshwater but it can tolerate brakish or salt water. They have benefitted from human hunting of larger crocodiles since Caiman leather is not good quality.

Like several lizards in the tropics, they can regulate body temperature by becoming lighter or darker.
