Known human health impact? | Not known Comments: Not available. |
Known economic impact? | Known References: Roscoe, C. M. 2005. Three factors affecting the invasion of Watersipora subtorquata in the marine fouling community of Humboldt Bay, California. Comments: Watersipora spp. have long been known to be tolerant of copper and mercury in antifouling paint. Their hard encrusting colonies are tolerant of moving water, and their colonies also provide non-toxic points of attachment for other organisms, allowing a diverse fouling community to develop, which can adversely affect the speed and efficiency of ships. |
Known measurable environmental impact? | Known References: Sellheim, K., Stachowicz, J. J., & Coates, R. C. 2010. Effects of a nonnative habitat-forming species on mobile and sessile epifaunal communities. Marine Ecology Progress Series, 398, pp. 69-80. Comments: Watersipora subtorquata colonies provide habitat for other organisms. Its colonies often develop elevated leaf-like folds rising above the substrate, creating additional space for colonization by other organisms. |

Association with vessel vectors (?) | Biofouling References: Ryland J.S., De Blauwe H., Lord R. & Mackie J.A., 2009 – Recent discoveries of alien Watersipora (Bryozoa) in Western Europe, with redescriptions of species – Zootaxa 2093:43-59 Mackie J.A., et al., 2006 – Invasion patterns inferred from cytochrome oxidase I sequences in three bryozoans, Bugula neritina, Watersipora subtorquata and Watersipora arcuata. Marine Biology 149: 285-295. Comments: Because its larvae spend less than a day in the plankton before settling, Watersipora subtorquata could not have been transported long distances as larvae in currents or in ballast water. While long-distance transport as adults on bits of seaweed or debris in currents or ballast tanks is theoretically possible, it seems unlikely. It is common in fouling and has often been found on ship bottoms, and is highly tolerant of copper-based anti-fouling compounds. |
