The green thornytail iguana can reach about 9 cm (3.5 in) in snout–vent length and has a relatively short, spiny tail.^[3] It has three distinct subspecies,^[2] which sometimes have been recognized as separate species:^[4] the nominate subspecies is bright green with distinct blackish bands and is found in the northeastern part of the green thornytail iguana's range, the southwestern T. a. guentheri is duller with greyish or brownish rear body and tail, and the northwestern T. a. werneri is almost all green without distinct markings in adults.^[2][3]
