Yucatan Spiny-tailed Iguana
Ctenosaura defensor (Cope, 1866)

The Yucatan Spiny-tailed Iguana Ctenosaura defensor is a small colorful iguana of the Yucatan peninsula (the actual range may differ from the map due to the fact that there is a lot of unexplored and unstudied areas of the Yucatan). Being the smallest of the genus Ctenosaura, males of this species have a snout/vent length of 145 mm (5 3/4 inches) with females being a little smaller. Like most of the other club-tail iguanas, this is a stout little iguana with a heavily armored tail. The head color of this iguana is generally bluish. The shoulders, forelimbs, and chest are black with white spotting. The lower back is red, and the tail is gray. From fecal examinations, C.defensor is believed to be primarily a leaf eater. Native people call this lizard “Chupito”, and believe it to be poisonous. Native people report that this species lays 2-3 eggs. Being a shy species, C.defensor probably spends a good amount of time hiding in hollow tree trunks, holes in the ground or holes in rocky areas.
