The Galapagos Islands have a low biodiversity (that is, few species), because the islands are 600 miles from the nearest land and this huge expanse of inhospitable ocean in-between makes it very difficult for new kinds of plants and animals to reach the islands. Marine organisms, such as green sea turtles and corals, probably came on their own, swimming, or as floating larvae. Sea birds are all strong flyers that frequently make long journeys across the open sea. But most of the Galapagos life forms reached the islands by accident, and all had a long sea voyage. During that trip, both plants and animals were exposed to saltwater, drying winds, and intense sunlight. They had no fresh water or food. Galapagos reptiles are also more likely than land birds or mammals to be able to survive under these conditions. As a result, animals of the Galapagos Islands are species whose ancestors were already well suited for its harsh environments. Compared to elsewhere in the tropics there are few birds or Galapagos mammals, and many important groups are missing.
