Watersipora n. sp.
Taxonomic Group: Bryozoans


Watersipora (here called n. sp.) is a new species which was identified from California harbors using molecular methods. Its origin and worldwide range are unknown, but its spotty distribution on the California coast is suggestive of being introduced. Aside from the California records, it has been collected from one location in South Korea. It is an encrusting calcified bryozoan known from rocks, pilings, floats and fouling plates. Because it is a newly identified species, knowledge of its impacts is limited. However, it has been found overgrowing large areas in some bays/harbors and experimental plate data show that the three-dimensional structure created by Watersipora n. sp. may increase local diversity in the fouling community.
