Marine Iguana at Puerto Ayora, Santa Cruz, Galapagos Islands
Best viewed Large on Black
According to Wikipedia, The Marine Iguana is an iguana found only on the Galapagos Islands that has the ability, unique among modern lizards, to live and forage in the sea, making it a marine reptile. The Marine Iguana can dive over 30 feet (10 m) into the water. It has spread to all the islands in the archipelago and is sometimes called the Galapagos Marine Iguana. It mainly lives on the rocky Galapagos shore, but can also be spotted in marshes and mangrove beaches.
Researchers theorize that land and Marine Iguanas evolved from a common ancestor since arriving on the islands from South America, presumably by rafting. It is thought that the ancestral species inhabited a part of the volcanic archipelago that is now submerged.
