Oplurus cuvieri
Oplurus cuvieri, commonly known as the collared iguana, the collared iguanid lizard, Cuvier's Madagascar skink, Cuvier's Madagascar swift, and the Madagascan collared iguana, is a species of arboreal lizard in the family Opluridae. The species is native to Madagascar and Comoros. There are two recognized subspecies. O. cuvieri is the largest of six species in the genus Oplurus.

Etymology
The specific name, cuvieri, is in honor of French naturalist Georges Cuvier.

Description
As some of the common names suggest, O. cuvieri has a distinctive black collar that stands out against the body which is speckled with lighter spots.  It has a large head, and the relatively short tail has spiny scales. The female is a duller brown colour.

The images below show considerable variation in markings and coloration.

Geographic range
The collared iguana is found in the western tropical forests of Madagascar and on the island of Grand Comore in Comoros.

Subspecies
Two subspecies are recognized as being valid, including the nominotypical subspecies.
Oplurus cuvieri cuvieri  – Madagascar
Oplurus cuvieri comorensis  – Grand Comore Island

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Oplurus.

Diet
O. cuvieri has a mostly carnivorous diet.

Reproduction
Breeding of O. cuvieri is timed with the rainy season.
