Cyclura – Rock iguanas/Cycluras
Large-bodied, herbivorous lizards found nowhere else than West Indies
Some of the world’s most threatened lizard species belong to the genus Cyclura. According to the IUCN Red List of Threatened Species, of the 16 officially recognized species and subspecies, five are endangered, and eight are critically endangered.
These iguanas have a long, straight tails, short, strong limbs, sharp claws, and a huge skin flap called a dewlap that hangs from the throat and helps regulate body temperature. Dark greys to light browns are some of their color options, and there is some obvious banding. To withstand hunger, they store a lot of fat around their necks.
