Polyandrocarpa zorritensis
Taxonomic Group: Tunicates


Polyandrocarpa zorritensis is a colonial tunicate, whose colonies consist of a cluster of club-shaped zooids, connected by stolons. It was first described from Zorritos, Peru in 1931, but its native region is currently unknown and may include the southeastern Atlantic or southwestern Pacific. It has a broad global distribution, being introduced to the East and West coasts of North America, Hawaii, the Mediterranean, and Japan. It has been reported on man-made and natural habitats, being found on marina docks, vessel hulls and mangroves. Polyandrocarpa zorritensis has been reported to overgrow the commercially important oyster, Crassostrea gigas, in Spain; and may be competitively dominant in fouling communities in Southern California.
