Caimans are alligatorid crocodylians within the subfamily Caimaninae. Caimans inhabit Central and South America. They are relatively small crocodilians, with most species reaching lengths of only a few meters, although one species, the Black caiman, can exceed 4 metres (13 ft) in length.[1]

Anatomy

Brain

In Caiman the dura covering the medullary region of the brain is proportionally thicker than the dura covering the forebrain, although this might not impact the ratio in volume between the regions.[2]
