The Galapagos archipelago is made up of thirteen main islands and more than sixty other islets, rocks and reefs, scattered over four hundred kilometres of open ocean. Sitting at a confluence of four major ocean currents, the islands are actually the summits of vast undersea volcanoes, and are steadily on the march. How has such an odd assortment of life managed to find a footing in this unruly world? Micro-climates and altitude have combined to form discrete environmental zones: perfect habitats for the islands diverse fauna marine iguanas, petrels, blue-footed boobies and giant tortoises being but a famous few. Galapagos is a rare insight into an incredible landscape, a natural laboratory and an exquisite evolutionary habitat that Darwin described as a 'world within itself'. Both fragile and furious, the Galapagos is unlike any other place on earth.
