The marine wildlife of Baa Atoll consists of marine species that live in a circular archipelago in the Maldives, inside the administrative division of Baa Atoll, which is the southern part of Maalhosmadulu Atoll. Baa Atoll was named a biosphere reserve by UNESCO in 2011.[1]

The whole is approximately 38 km by 46 km, covering a surface of 1 127 km².[2] However, the atoll shelters only 5,5 km² of emerged land, consisting of sandy islands not higher than 3,19 m, and of which half do not exceed an area of 10 hectares. Administrative subdivision of Baa shelters 11 910 inhabitants, distributed on 13 of the 75 islands, 8 other islands being island resorts; the capital is Eydhafushi.

The archipelago is located inside the eponym UNESCO Biosphere reserve since 2011.[1] Its shallow waters, particularly rich in coral and fish as well as turtles and dolphins, made a favored place for seaside and underwater tourism.[1]

The ecosystem is characterized by a very high rate of coral cover, highly diverse and dominated by table, digitate and branched corals of the genus Acropora. The shallow waters of this atoll and its particular richness in corals and fish have made it destination for underwater tourism.[1] The presence of huge animals such as Manta rays or whale sharks add spectacular encounters to the beauty of the place.[3]
