The green thornytail iguana (Uracentron azureum) is an arboreal species of lizard from the Amazon rainforest and forests in the Guiana Shield. It is found in Colombia, Guyana, Suriname, French Guiana, northeastern Peru, southern Venezuela and northern Brazil. In addition to the nominate subspecies from the northeastern part of its range, it has two subspecies: the southwestern T. a. guentheri and the northwestern T. a. werneri. It can reach about 9 cm (3.5 in) in snout–vent length, has a relatively short spiny tail, and is overall green with black spots and bands. As in U. flaviceps (the only other species in the genus), U. azureum primarily feeds on ants.
