About Oplurus quadrimaculatus Duméril & Bibron, 1851
Oplurus quadrimaculatus, commonly known as the Madagascar spotted spiny-tailed iguana, can reach a total length of 25–39 centimetres (9.8–15.4 in). This iguana has a greyish base color, with spotted patterns across its back and tail. Its legs are covered in enlarged, spinous scales. Individuals of this species spend hours basking in sunlight, and they are mainly insectivorous. Mating in this species lasts only a few seconds, and females lay their eggs in sheltered locations. This species is endemic to Madagascar, where it occurs from central Madagascar through the southern part of the country, at elevations up to 2,050 metres (6,730 ft) above sea level. It inhabits loamy slopes, clay expanses, and large rocks across a wide range of environments, including arid dry spiny forests, northern wetlands, humid areas adjacent to rainforests, and shrubland.
