Description: Overview of marine iguana habitats, feeding patterns, and behavior.
Marine Iguanas are certainly among the most unusual creatures in the Galapagos. Charles Darwin made extensive observations on these large, lizard-like reptiles. They certainly well demonstrate the unique evolution and adaption of Galapagos fauna. The males, which are larger than the females, may grow to a length of 4 feet or more (almost half of which is tail). They look fearsome (Darwin called them "hideous"), but are quite harmless. These herbivores feed exclusively on algae growing on rocks near the shore. When feeding, they can remain submerged for up to an hour, though dives of 5 to 10 minutes are more common. The water in the Galapagos is often quite cold and being cold-blooded, iguanas spend much of their time restoring body heat by sunning themselves on the rocks adjacent the shore. Like many of the Galapagos animals, they are usually unperturbed by the presence of humans and may be approached quite closely (this is more true in the populated area around Academy Bay than in more remote areas). The closely related land iguana is lighter colored and usually somewhat larger. It is also less common and often somewhat shy.
