Description
editPolyclinum aurantium forms globular or flat-topped mounds consisting of a number of zooids immersed in a common tunic. Each zooid has its own buccal siphon with six lobes, through which it draws in water, and the colony has a small number of common cloacal siphons, each with a long tongue-like projection, through which water is expelled. The individual zooids are up to 6 mm (0.24 in) long, and the colony is yellowish-brown or yellowish-grey and often coated with sand.[2]
Distribution and habitat
editPolyclinum aurantium is native to the northeastern Atlantic Ocean. Its range extends from Norway southwards to the Mediterranean Sea. It occurs on rocks and other hard substrates at depths down to about 100 m (328 ft).[2]
