:  The Black Corals
Anthozoa: Black Corals
Body Form: Thin and wiry skeletons that are either branched or unbranched, with small polyps extending along the rind surface.
Natural History: The Black Corals are found worldwide at sport diving depths and beyond. They feed on microplankton in the water column and use the products of zooxanthellate algae for nutrition. They are declining because of the overcollection and use of their flexible skeletons for the production of jewelry.
