Marine Iguanas vary greatly from island to island. This one shows the bright red that's characteristic of specimens from Espanola Island. They bask on the dark lava rocks at water's edge, sometimes in great numbers (see other photo); they swim gracefully (see other photo); and they ignore human intrusion (see other photo).

Some paths were carefully marked so visitors wouldn't wander into sandy areas where Marine Iguanas had deposited their eggs.

Amazingly, these lizards dive to depths of 20 feet or more to gain access to the underwater plant life on which they feed. It's theorized their blunt faces are an adaptation that facilitates their tearing the plants on which they feed from underwater rocks.
