Black spiny-tailed iguana

Ctenosaura similis


"The largest members of the genus Ctenosaura, males are capable of growing up to 1.5 meters (4 ft 11 in) in length and females slightly shorter at 1 meter (3 ft 3 in). They have a crest of long spines which extends down the center of the back. Although coloration varies extremely among individuals of the same population, adults usually have a whitish gray or tan ground color with a series of 4–12 well-defined dark dorsal bands that extend nearly to the ventral scales."
