Marine iguanas are unique to the Galapagos Islands, which are located near Ecuador (off the western coast of South America.) They are reptiles and cold blooded, so they need heat to warm their bodies.

Unlike most lizards, these iguanas
are vegetarians. To feed, they’ll dive into the cool waters of the Pacific to munch on seaweed that is found in the tidal pools.

They’ll eat quickly, since their body temperature can drop rapidly. The iguana will then return to the sun-warmed volcanic rocks that line the shores.

They live in colonies and often lay one on top of the other to preserve heat. It’s not unusual to see a whole pile of iguanas haphazardly heaped together. Marine iguanas blend in perfectly with this environment.
