:  Clavulariidae
Taxonomy: Alcyonacea: Clavulariidae (Octocorals)
Body Form: A Clavularian consists of a colony of erect polyps with tentacles that are feathery or bare. Sclerites of calcite are present to reinforce an upright stalk.
Diet: The octocorals are generally polytrophic - getting nutrition from zooxanthellae (algae) in their tissues, nutrient uptake from the seawater, and feeding on microplankton.    Care Level:  easy
Natural History: The Alcyonacea (one of the octocorals) include the leather corals, soft corals, map polyps, and gorgonians. Nearly all members live attached to a solid substrate by attachment via a holdfast. As a group they do not produce an aragonite skeleton but instead produce a protein and calcite that together cements the body together. Lacking penetrating nematocysts, these corals feed on tiny prey - bacteria, rotifers, and algae cells - that are suspended in the water column. They are found in areas without high wave action. Some species produce exotoxins that may affect the growth of other stony coral competitors.
