Amblyrhynchus

Amblyrhynchus is a monotypic genus of lizard, family Iguanidae, containing the single living species the marine iguana, found only on the Galapagos Islands of Ecuador. It is the only extant lizard that spends time in a marine environment, with the ability to forage in the sea for algae, which make up almost all of its diet; larger males can dive for food in deeper water, while females and smaller males feed in shallow intertidal zones during low tide. The genus lives in colonies on rocky shores as well as in marshes, mangrove swamps and beaches.
