Black Spiny-Tailed Iguana

Range

Native to southern Mexico and Central America, but introduced populations are established in coastal southern Florida.

Habitats

They love to climb and prefer rocky habitats with lots of trees and sun. They can be found in savannahs, coastal lagoons, beaches, farmland, marshes, and urban areas.

Identification

A moderately large species of iguana named for the even rows of spiny keeled scales on its tail. It averages 3-4 feet in total length. It has a single row of elongated pointy scales down its spine. Adults are primarily light grey with black bands on the body. They are sexually dimorphic. Males are heavier-bodied and longer, have large jowls, and their dorsal spikes are much longer. Breeding males also develop orange, blue, and pink coloration on their head, throat, and jowls. Females are usually dull grey-brown with little to no banding.
