Coral \Cor"al\, n. [Of. coral, F, corail, L. corallum, coralium,
   fr. Gr. kora`llion.]
   1. (Zo["o]l.) The hard parts or skeleton of various Anthozoa,
      and of a few Hydrozoa. Similar structures are also formed
      by some Bryozoa.

   Note: The large stony corals forming coral reefs belong to
         various genera of {Madreporaria}, and to the hydroid
         genus, {Millepora}. The red coral, used in jewelry, is
         the stony axis of the stem of a gorgonian ({Corallium
         rubrum}) found chiefly in the Mediterranean. The {fan
         corals}, {plume corals}, and {sea feathers} are species
         of {Gorgoniacea}, in which the axis is horny.
         Organ-pipe coral is formed by the genus {Tubipora}, an
         Alcyonarian, and {black coral} is in part the axis of
         species of the genus {Antipathes}. See {Anthozoa},
         {Madrepora}.

      They are classed as {fringing reefs}, when they border the
      land; {barrier reefs}, when separated from the shore by a
      broad belt of water; {atolls}, when they constitute
      separate islands, usually inclosing a lagoon. See {Atoll}.
