Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea near major shipping routes. The largest of the six islands in the Socotra archipelago, it comprises around 95% of the landmass of the archipelago. It lies 380 kilometres (205 nautical miles) south of the Arabian Peninsula and 232 km (125 nmi) east of the Horn of Africa. The inhabitants of the island are called Socotrans, and they speak Arabic and Soqotri.
Socotra is home to a high number of unique species that are endemic. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures 132 km (82 mi) in length and 42 km (26 mi) across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site.
