For example, Cozumel, Mexico, was famed for dense black coral beds that have been harvested since the 1960s [30] leading to widespread black coral population declines. [31] Despite improvements in management in Cozumel, including no harvesting permits issued since the mid-1990s, the black coral population had failed to recover when assessed in ...
The Flower Garden Banks National Marine Sanctuary (FGBNMS) is a United States National Marine Sanctuary located 100 nautical miles (120 mi; 190 km) off of Galveston, Texas, in the northwestern Gulf of Mexico. It contains the northernmost coral reefs in the United States. Underlying salt domes forced the seafloor upward in various areas of the ...
Black corals are so called because the main axial skeleton is made of a spiny, keratin-like substance called "antipathin" which is a dark brownish-black. This colonial coral has a bushy, two dimensional form and grows out of a holdfast firmly anchored to a rock. It can grow to 1.5 m (5 ft) tall and a similar width.

While, most azooxanthellate corals are flexible and tend to flow with the currents, T. micranthus is rare in that it is a reef-building coral, strong enough to remain standing in areas that were blasted with dynamite. They are additionally notable for their relatively fast rate of growth of 4 cm per year, outpacing many azooxanthellate corals. [2]
Cozumel's deeper coral reefs were historically famed for their black corals, [9] yet black coral populations declined from the 1960s to the mid-1990s because of overharvesting [9] and by 2016 had not recovered. [10] The reefs there are made up of hard coral and soft coral.
Oculina is a genus of colonial stony coral in the family Oculinidae. These corals are mostly found in the Caribbean Sea, the Gulf of Mexico and Bermuda [2] but some species occur in the eastern Pacific Ocean. They occur at depths down to 1000 metres. [1]
