Most vertical surfaces of the Wall Panama City, Florida, USA were covered with dense sponges, algae, octocorals, and black corals. 6 Centro Nacional de Áreas Agaricia was the most abundant scleractinian genus on the Wall at Protegidas, La Habana, Cuba depths of 50-75 m, and was observed to 122 m. Of the 2,240 sclerac- tinian colonies that were counted in this study, only 12 corals (0.53%, 7 Acuario Nacional de Cuba, La Habana, Cuba mainly Agaricia spp.) showed signs of bleaching, and one Agaricia had black band disease, comprising remarkably low disease preva- 8 Geocuba Estudios Marinos, lence.
