Chapeirão Faca Cega

Chapeirão Faca Cega is a chapeirão formation endemic to southern Bahia, cut through by several passages and tunnels that link the great massif. It is about 35 m tall and has an interior chamber where you can dive, almost 20 m in diameter, as well as several passages and burrows.

It is a dive full of color, with corals and reef fish, and rays are sometimes seen. Among the reef-building corals are M. hartti, M. híspida, M. alcicornes, Montastrea cavernosa and Agarícia fragilis, as well as the endemic brain coral M. brasiliensis. Among the fish there are parrotfish known locally as budiões and schools of dentão, and in 2019 reef monitoring recorded Mycteroperca bonaci and Scarus trispinosus on the chapeirão.

In the 2019 heat wave, Faca Cega had the lowest fire coral mortality among the monitored sites, about 63%. In Abrolhos, summer, from December to February, usually brings warmer water and is the recommended period for diving in the region.
