''Polyclinum aurantium'' is a species of colonial sea squirt, a tunicate in the family Polyclinidae. It is native to shallow water in the northeastern Atlantic Ocean and Mediterranean Sea. ==Description== ''Polyclinum 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 long, and the colony is yellowish-brown or yellowish-grey and often coated with sand.
