Watersipora subtorquata complex
Taxonomic Group: Bryozoans

Overview:

Watersipora subtorquata is an encrusting bryozoan widely distributed around the globe. Its colonies can be erect and leaf-like, with extensive overlapping calcareous crusts and curled edges, which create secondary habitat for the settlement of other marine invertebrates. Its native range is poorly understood because of taxonomic confusion with related species, particularly W. subovoidea. However, introduced populations have been recorded on the West coast of the United States, Hawaii, Australia, New Zealand, Europe, and South Africa. This species is known from rocks, oyster shells, pilings, floats, oil platforms, ships' hulls, and fouling plates. It is tolerant of copper and mercury antifouling paints and has outcompeted congeneric species in some areas of its introduced range.
