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