Socotra or Soqotra (Arabic سُقُطْرَى ; Suquṭra) is a small archipelago of four islands in the Indian Ocean. The largest island, also called Socotra, is about 95% of the landmass of the archipelago. It lies off some 240 kilometres (150 mi) east of the Horn of Africa and 380 kilometres (240 mi) south of the Arabian Peninsula. The island is very isolated and through the process ofspeciation, a third of its plant life is found nowhere else on the planet. It has been described as the most alien-looking place on Earth. Socotra is part of the Republic of Yemen. It has long been a part of the 'Adan Governorate, but in 2004 it became attached to the Hadhramaut Governorate, which is much closer to the island than 'Adan (although the closest governorate would be Al Mahrah).
