Marine Iguana

In addition to the Land Iguana, the Galapagos is home to the Marine Iguana.  They are the only lizard to be ocean-going thanks to their marine adaptations and unique evolution of biology.  These iguanas are found on all of the islands in the Galapagos but nowhere else in the world.  They have a shortened snout with small teeth allowing them to graze on algae and have a means of extracting excess salt from their blood flow and sneezing it out several times a day.  Their life span is slightly shorter than the land iguanas at around 40 years old and they differ in size depending on which island you are visiting.
