A little information about Socotra for those interested, I myself have  to read up on it, I only knew about this island 2 months ago when I  googled Yemen to prepare for my trip there.As for the title some people  dubbed it as "Indian Ocean's Galapagos" because of the diverse animal  and plant life that exist in the island most are endemic.
S O C  O T R A :
Socotra or Soqotra (Arabic سقطرى ; Suquṭra) is a  small archipelago of four islands and islets in the northwest Indian  Ocean near the Gulf of Aden. Nearly 190 nautical miles (220 mi/350 km)  south of the Arabian Peninsula, the archipelago is 250 kilometers (155  mi) long, west to east, and protracts from continental Africa along the  Horn of Africa. It is part of the Republic of Yemen.
The  islands are known for unique flora and fauna, of which 37 percent of its  plant species, 90 percent of its reptile species and 95 percent of its  land snail species are not found anywhere else. Globally significant  populations of land and sea birds (192 bird species, 44 of which breed  on the islands while 85 are regular migrants) are supported 
on Socotra. This number includes a number of  threatened species. The region's marine life also displays great  diversity. In and around Socotra 253 species of reef-building corals,  730 species of coastal fish and 300 species of crab, lobster and shrimp  exist.
This archipelago of rich biodiversity was designated a  UNESCO World Heritage Site in 2008. The main island, as one of the most  biodiversity rich and distinct islands in the world, has been termed the  “Galápagos of the Indian Ocean.” Its name is believed to come from the  Sanskrit 'dvipa sakhadara', which can be translated as 'Island of Blis
GEOGRAPHY AND CLIMATE:
Socotra is one of  the most isolated landforms on Earth of continental origin (rather than  volcanic origin). The islands of the archipelago stand on coral banks  and are believed to have once been connected with the African and  Arabian mainlands as part of the ancient southern supercontinent of  Gondwana. They detached during the Middle Pliocene (ca 6 million years  ago), in the same set of rifting events that opened the Gulf of Aden to  its northwest.
The archipelago consists of the main island of  Socotra (3,625 km² or 1,400 sq mi), 
the  three smaller islands of Abd al Kuri, Samhah, and Darsa, and small rock  outcrops like Ka’l Fir’awn and Sābūnīyah that are uninhabitable by  humans but important for birds.
Socotra is the largest island  in the Arab world, of an estimated total of 258 islands occupying an  area of 6,811 km², dispersed throughout the region stretching from the  Persian Gulf to North Africa's Maghreb in the Mediterranean Sea.[1]
The main island has three geographical terrains: the narrow coastal  plains, a limestone plateau permeated with karstic caves, and the  Haghier Mountains. The mountains rise to 5,000 feet (1,525 m). The main  island is a little over 80 miles (130 km) long east to west and  typically 18-22 miles (30-35 km) north to south.
The climate is  generally tropical desert, with rainfall being light, seasonal, and  more abundant at the higher ground in the interior than along the  coastal lowlands. The monsoon season brings strong winds and high seas.
FLORA AND FAUNA:
Socotra is rich in terms of  biodiversity, comparing favorably with such island groups as Galapagos,  Mauritius, and the Canary Islands. It has been referred to as the  "jewel" of biodiversity in the Arabian Sea. 
The long geological  isolation of the Socotra archipelago and its fierce heat and drought  have combined to create a unique and spectacular endemic flora. Surveys  have revealed that of a total of nearly 900 species, a 37 percent are  endemic; ranking it in the top five islands in terms of endemic flora.  Botanists rank the Socotra flora among the ten most endangered island  flora in the world, vulnerable to introduced species (such as goats),  climate change, and modernization. The archipelago is a site of global  importance for biodiversity conservation and a possible center for  ecotourism.
One of the most striking of Socotra's plants is the  dragon's blood tree (Dracaena cinnabari), which is an unusual looking,  umbrella-shaped tree. Lore has it that its red sap was the dragon's  blood of the ancients, sought after as a medicine and a dye. Another  unusual plant is Dorstenia gigas, a succulent that can grow to eight  feet tall and have a trunk of up to two feet or more in diameter.
The  island group also has a fairly rich bird fauna, including a few types  of endemic birds, such as the Socotra Starling Onychognathus frater, the  Socotra Sunbird Nectarinia balfouri, Socotra

As with many isolated island  systems, bats are the only mammals native to Socotra. In contrast, the  marine biodiversity around Socotra is rich, characterized by a unique  mixture of species that have originated in far-flung biogeographic  regions: the western Indian Ocean, the Red Sea, Arabia, East Africa and  the wider Indo-Pacific.
