Marine Iguana

The Galápagos Islands are the only place where the marine iguana (Amblyrhynchus cristatus), commonly known as the sea iguana, saltwater iguana, or Galápagos marine iguana, may be found (Ecuador). It is a marine reptile that is distinct from other contemporary lizards in that it can forage in the sea for algae, which accounts for approximately all of its diet. The only living lizard that regularly spends time in a marine environment is the marine iguana. While females and smaller males forage in the intertidal zone at low tide, large males can dive to reach this food supply.

They can be found in marshes, mangrove swamps, and beaches, although they typically live in colonies on rocky coasts where they bask after swimming in relatively cold water or the intertidal zone. Smaller men have various methods of mating while larger males only defend their territories for a brief time. After mating, the female creates a nest hole in the ground, lays her eggs, and then waits a few months for them to hatch on their own.
