Galapagos Marine Iguanas

Marine Iguanas are very unique creatures. They are the only swimming reptiles in the world that are still alive. They can reach depths of 30ft, but can only stay under for about 10 minutes because they are cold blooded. Their population is somewhere in the hundreds of thousands and they live for 5-12 years. When eating, they intake too much salt, so they use glands on their heads to expel it. They are thought to come from other South American lizards and they adapted for diving.

The Galapagos are special islands because of the diversity they contain. They shift and rotate and many are volcanicly active.
