Mysterious Islands Are A Hotspot For Marine Hybrids

Some 150 miles off the eastern coast of northern Africa — about 240 miles south of the Arabian peninsula — lies a set of islands that some have called “the most alien-looking place on Earth.” Socotra, which is both the name of the archipelago and the largest island, is a truly bizarre place. More than a third of the plants that erupt from the soil are found nowhere else. Their odd shapes and forms give the islands a Dr. Seussian quality, an almost cartoonish, comical landscape that stands in sharp contrast to the strict religious practices of the people who live there.

Socotra is a part of Yemen, a country currently engaged in a brutal civil war. But, it is also an island apart; the hundreds of miles of water that separate Socotra from the mainland have not only allowed biodiversity to take otherworldly forms, they have also allowed the people of Socotra to become distinct. The 50,000 or so people that live on the islands have their own language, myths and legends, and are their own governorate. Socotra has an archeological history that dates back to some of the earliest civilizations, complete with inexplicable cave art and 2,000 year old tools. The rich culture of the indigenous Soqotri has been insulated, like the flora and fauna they live alongside, for thousands of years — until the past decade, or so, when the Yemeni government has begun to open the islands to tourism.

In 2008, the United Nations Educational, Scientific and Cultural Organization (UNESCO) declared the islands a world heritage site, citing the incredible uniqueness and diversity of the land’s plants and animals — the “Galápagos of the Indian Ocean.” In addition to the hundreds of endemic plants, more than 90 percent of the reptiles and land snails that live on the islands are exclusive to them. Culturally and ecologically, Socotra is a place where uniqueness flourishes.

But the uniqueness of Socotra doesn’t end at the waters’ edge. Scientists have found that its coral reefs are pretty special, too — they’re home to a heap of hybrids. Continue reading “Mysterious Islands Are A Hotspot For Marine Hybrids”
