About The Galapagos:
The Galapagos Islands were formed about 3-5 million years ago. They are the tips of gigantic undersea volcanoes and the area is one of the world's most active volcanic regions. Some of the volcanoes are still active and there have been over 50 eruptions in the last 200 years. Each island is a volcano, except Isabela, which is made up of 6 volcanoes. The archipelago is made up of 13 large islands, 6 smaller ones and 107 rocks and islets, and is home to more than 5,000 different species.
Animal life
Galapagos is home to many unique, endemic animals, most of which are fearless due to the lack of natural predators. One of the best known, the giant tortoise, has evolved into fourteen distinct forms on the different islands of the archipelago. Other reptiles include the marine iguana which grazes on seaweed, land iguanas, lava lizards, geckos and snakes. The only terrestrial mammals are rice rats and two species of bat. The 13 species of small, brownish finches are adapted to a range of different foods and are known collectively as Darwin's finches. They have been important to scientists trying to understand how evolution occurs, and include the tool-using woodpecker finch. Other endemic (only found in Galapagos) land birds include a hawk, dove, flycatcher, rail and four species of mockingbird.
Among the endemic sea birds are a flightless cormorant, two species of gull, and the only penguin species which lives in tropical waters. The waved albatross breeds solely on Espa__ Island, while colonies of blue-footed, red-footed, and masked boobies are found alongside frigatebirds. Sea lions and fur seals are found around the coasts, while dolphins, whales and sea turtles are common. Over 300 species of fish have already been described from the rich ocean waters around the archipelago. There are also at least 1,600 species of insects, 80 spiders, 300 beetles, 150 mites, 80 land snails, 650 sea shells ,200 starfishes and urchins, 120 crabs, and many other smaller animals.
Plant life
The plants of Galapagos are equally fascinating. In the highlands are many species of endemic Scalesia ('tree daisies') as well as tree ferns, bromeliads and orchids. Around the coasts are giant prickly pear and candelabra cacti while tiny Brachycereus cacti grow on barren lava flows. On the shores can be found vivid morning glories and mats of bright red sesuvium. Galapagos also has its very own, endemic species of cotton, tomato, pepper, guava and passion flower. Many kinds of plants, particularly those belonging to the daisy family, have evolved on the different islands into whole arrays of endemic species, providing scientists with classic examples of what is known as 'adaptive radiation'.
