The islands that changed the world. The Galapagos islands are a fascinating microcosm of our planet and home to some of the most astonishing creatures found anywhere on Earth: iguanas swim the sea like dragons, short-eared owls stalk petrels by day and 500 pound giant tortoises bellow over lava fields. One thousand kilometers due west of Ecuador, where four major ocean currents unite, vast undersea volcanoes break the surface of the Pacific Ocean. Early explorers described these otherworldly islands as "Las Encantadas" - "the Enchanted Isles," but in time they became known as "Galapagos," the "Islands of the Tortoises." Using spectacular HiDefinition cinematography from land, sea and air, and blending dramatic landscapes with intimate animal behavior, drama reconstruction and stunning satellite imagery, this ambitious series presents the most complete portrait ever of these fascinating islands. Galapagos reveals how wildlife has found the most enterprising ways to survive on this restless volcanic outpost, why these islands are such a fascinating showcase for evolution, and the profound forces that influence the delicate balance of life. Against a backdrop of smoldering volcanoes, brittle lava fields, fields of giant cactus and wave-pounded shores, witness blue-footed boobies plunge-diving into treacherous waters, sea lions surfing, the beautiful courtship dance of the waved albatross, Darwin's finches as crafty tool-users and hawks hunting marine iguanas. Galapagos is unlike any other place on Earth.
