All crocodilians in the genus Caiman have a pyramidal shape to their eyes, due to the heavy ossification of the upper eyelid. If this shape is seen above a crocodilian’s eye, you have narrowed it down to one of three species: Caiman crocodilus, Caiman yacare, or Caiman latirostris.

They have ISO’s only on their heads.

Front feet do not have webbing.
