Schizoporella japonica
Taxonomic Group: Bryozoans


Schizoporella japonica is a heavily calcified encrusting bryozoan which is native to the Northwest Pacific, from China to Northern Japan. Introduced populations are known from the West Coast of North America ranging from Alaska to Point Conception, California. The full extent of its native and introduced range is uncertain because of confusion with S. unicornis, S. errata, and other Schizoporella species. Schizoporella spp. are common fouling organisms and frequently dominate the fouling community on man-made structures such as ships' hulls and docks.
