Iguanas Quiz – Lizards of Sun and Sea

Iguanas are large lizards found mainly in Central and South America, the Caribbean and the Galápagos Islands. Most are plant-eaters with spiny crests, strong tails and a skin flap called a dewlap under the chin.

The marine iguana of the Galápagos is the only lizard that feeds in the sea, diving for algae and sneezing out excess salt. Green iguanas live in trees and can survive long falls, while land iguanas eat cactus on dry islands.

Several iguanas are endangered, including the Grand Cayman blue iguana and the Galápagos pink iguana. Invasive predators like cats and dogs threaten them, while introduced green iguanas have become pests in Florida.
