The marine life of Socotra is also very diverse, with 253 species of reef-building corals, 730 species of coastal fish and 300 species of crab, lobster and shrimp, and well represented in the property's marine areas.
Some 250 million years or more ago, when all the planet's major landmasses were joined and most major life-forms roamed freely from one region to another, Socotra already stood as an island apart.
Ever since Socotra has been a breeding ground of birds, plants and animals. The isolation from other land masses meant whatever evolutionary process the flora and fauna underwent never spread to the mainland.
One of the most striking of Socotra's plants is the dragon's blood tree (Dracaena cinnabari), which is a strange-looking, umbrella-shaped tree.
