Galapagos Islands

Galapagos Islands 

Archipiélago de Colón, a group of islands in the Pacific Ocean below the equator and to the west of South America. The group belongs to Ecuador. Total area of the 16 islands, 7,800 sq km. Population, 3,100 (1967).

The Galápagos are volcanic in origin and covered with the cones of a large number of extinct and active volcanoes, which reach an altitude of 1,707 m. The climate is dry equatorial, but the cold Peru Current keeps temperatures moderate (yearly average temperature, 23° C). The vegetation is primarily of the xerophytic succulent shrub type. Representatives of tropical and antarctic flora and fauna—lianas and mosses, tropical birds and gulls from Antarctica, parrots and penguins, and seals—are found coexisting closely in the Galápagos. There is a great abundance of unique local species, such as the endangered giant tortoises and iguanas. The islands were declared a national park in 1965. Darwin used material drawn from his observations in the Galápagos to substantiate his theory of the origin of species.
