The skin of the Rhinoceros Iguana has gray-brown or olive-green scales that allow it to blend in with its surroundings. Males are larger than females, as are their horns. The mating season begins in May and the eggs are laid in nests about 40 days after intercourse. After laying eggs, the female can remain close to the nest to avoid possible predators. The Rhinoceros Iguana is native to the Spanish island of Hispaniola, lives in dry forest, scrubland or desert, preferably in coastal areas, although the action of man can cause them to move inland. Your current status is vulnerable.
