Reptiles: Rhinoceros Iguana

Image hosted by Photobucket.com


Adult rhinoceros iguanas reach large sizes and have heavily built bodies that are dark brown, greyish brown or even black in colour. The underside is typically lighter in colour than the upper surface, and the snout features three horny bumps, which are more prominent in males than females. Juveniles are generally similar in appearance to adults, although they have nine pale crossbars for a time after hatching.

The rhinoceros iguana can be distinguished from the other two subspecies, the now extinct Navassa Island iguana (C. cornuta onchiopsis) and the Mona Island iguana (C. cornuta stejnegeri), by certain detailed features, including the number of scales.
