The study also determined a tropical storm that passed over the area during summer 2010 churned up the sea and caused oil to reach the corals. [5] A 2005 National Academy of Sciences report showed that oil mixed with dispersants damaged certain corals' reproduction and deformed their larvae. The study concluded the federal government needed to ...
Black corals are mostly deep water animals; specimens (including fan-shaped and bottlebrush-shaped species) from the Gulf of Mexico, collected and recorded with remotely operated vehicles at depths ranging from 68 to 124 m (223 to 407 ft), revealed O. gracilis growing on six different species.
It contains the northernmost coral reefs in the United States. Underlying salt domes forced the seafloor upward in various areas of the Gulf of Mexico, resulting in the formation of seamounts and ocean banks. Conditions of the Gulf of Mexico were conducive to reef-building, which started roughly ten to fifteen thousand years ago.
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.
