The skeleton of a black coral is hard and inert, due to its composition of protein and chitin, making it nearly inedible. Though black coral skeletons have been found in the stomachs of green sea turtles and sharks, these incidents are rare; it has thus been suggested that black corals are not a major part of any vertebrate diets.

White "black coral". Gooseneck barnacles are attached to a branch in the lower right center. In the deep waters off Malta in the Mediterranean Sea, Leiopathes glaberrima is the dominant species in what have been called "coral gardens", where it is associated with other scleractinian corals, gorgonians and zoanthids. The areas are characterised ...
Calliophis nigriscens, commonly known as the black coral snake or striped coral snake, is a species of venomous elapid snake endemic to the Western Ghats, India. [3]
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.
No genuine coral snake in the U.S. exhibits red bands of color, in contact with bands of black, except in rare cases of an aberrant pattern. Thus, while on extremely rare occasions when a certain non-venomous snake might be mistaken for a coral snake, the mnemonic holds true.
Aphanipathes is a diverse genus of black corals in the family Aphanipathidae, typified by large polypar spines. [2] [3] However, there are some disagreement in the correct taxonomic classification of this genus.
Off the coast of Puerto Ángel in open ocean is a large, well developed coral reef area. This reef occupies a small ocean plateau that is 15 to 20 meters below the surface and about fifty to one hundred meters from the closest land. One of the most commonly found species is the black coral (Pocillopora damicornis). Large corals are rare and ...
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]
