Watersipora arcuata
Taxonomic Group: Bryozoans

Overview:

Watersipora arcuata is an encrusting bryozoan that was first described from San Diego Bay, California in 1969. Its native region is unknown, but it may be native to the eastern tropical Pacific. It appears to be introduced in California, the Pacific coast of Mexico, Hawaii, New Zealand, and Australia. It is found on pilings, rocks, floats, and ships' hulls and data suggest that it is a warm-water species which may be restricted in cooler waters, or outcompeted by W. subtorquata. Watersipora arcuata is notable for its ability to settle on surfaces covered with copper-based antifouling paints, and to survive on fast moving ships, its most likely introduction vector.
