Description
Gorgonians live on the sea bed in large colonies forming typical fan shapes and are oriented at right angles to prevailing water currents to capture plankton as they drift by. The branches are either primary or secondary, thin and flexible. Those on the outer edge of the fan are short and clavicular. The skeleton is horny and can be up to 3 or 4cm thick at the base. The body consists of an erect central rod of organic material called gorgonin, surrounded by a cylinder of calcareous spicules and by the polyp organisms, in branching, plant like forms. The spicules contain a pigment that gives the gorgonian its colour. polyps are a yellowish colour.
Biology
Reproduction is similar to that of other gorgonians of the same family. The habitat for the larvae needs to be precise. Growth rates vary but in optimum conditions can reach 6 cm per year. The splendid colours degrade when removed from the water.
