Marine Iguana

About Marine Iguana

The Marine Iguana is the only lizard in the world that goes into the ocean. It eats seaweed that grows near the shores of the Galapagos Islands where they live. It survives the cold temperatures by slowing down its heart rate when it dives. This helps prevent it losing too much heat through its blood when it is in the water. It is able to stay under water for up to twenty minutes at a time.

Marine Iguanas can get to be quite large, up to 5 ft. (1.5m) long. It has wide jaws, a blunt head, and its tail is flat and works like a rudder in the water.
