Located east of the Horn of Africa, Socotra is often called the most alien-looking place on Earth. An archipelago comprised of one large island with three smaller islands, Socotra contains nearly 700 species of plants and animals that can't be found anywhere else on the planet.
Scientists have found that almost one-third of the island's 800 plant species are found exclusively on Socotra. Of all the unusual flora on the island, the dragon's blood tree, famous for its bright red sap, is the tree most often associated with Socotra and the most photographed. The cucumber tree is also a popular feature on the extremely biodiverse island.
The only mammals native to the island are bats, though other mammals have been introduced over time. Socotra is filled with native reptiles and birds, including the Socotra starling, Socotra sunbird, geckos and legless lizards.
While technically a part of Yemen, Socotra is isolated in the Arabian Sea, about 220 miles from the mainland. The climate is mostly dry, though the island experiences light rainfall periodically throughout the year.
