Cayo Levisa

Cayo Levisa is a cay in Pinar del Río Province, Cuba. Accessible only through boats from Palma Rubia, the white sand beaches on its north coast attract tourism. It has several snorkeling and diving sites. It is part of the Colorados Archipelago coral reef and well known for its black coral. The cay is roughly 1.5 km (150 hectares) in size and 4.2 km long. It is several hundred yards wide in most points, with a maximum width of 750 m and a minimum of 280 m. It is located roughly 150 km west of Havana. Swamps cover more than three quarters of the surface of the island; the south side is inaccessible due to a forest of mangroves. The average temperature in Cayo Levisa is between 21 °C and 33 °C The Benthic zone of the coral reef was analysed in 2002 and 2003. Foliaceous and calcareous algae cover at least half of the substrate. Live coral cover was 30–40%, with ten dominant species of coral occurring more densely than sponges and gorgonians.
