Galapagos Island Wildlife Guide

Stretched along the equator, west of Ecuador, the Galapagos Islands’ 18 volcanic islands bask under blue skies for the majority of the year, making them a great place to travel to anytime. The islands were formed some 3-10 million years ago by volcanic activity that burst through the earth’s crust, creating this fascinating archipelago. Their isolated position, some 900km off the coast of Ecuador, and the movement of seven major marine currents have made the Galapagos Islands a unique breeding ground for animals and plant wildlife. These islands are home to a large number of endemic animals and plants which have adapted to their particular conditions over hundreds and thousands of years. When naturalist Charles Darwin traveled to the Galapagos in 1835, he was amazed by the different animals he found within the same species, and his observations became pivotal in the development of his theories on natural selection and evolution.
