| Known economic impact? | Known References: De Blauwe, H. Faasse, M. A. 2001. Extension of the range of the bryozoans Tricellaria inopinata and Bugula simplex in the North-East Atlantic Ocean (Bryozoa: Cheilostomatida). Nederlandse Faunistische Mededelingen, 14, pp. 103-112. Comments: It is a rapidly growing fouling organism, settling on vessels, pontoons, buoys and ropes and all other kinds of submerged organisms at the intertidal and upper subtidal levels. |
| Known measurable environmental impact? | Known References: Occhipinti-Ambrogi, A. 2000. Biotic invasions in a Mediterranean Lagoon. Biological Invasions, 2, pp. 167-176. Comments: The arrival and spread of T. inopinata in the Venice Lagoon caused a decline in the abundance of some bryozoan species with the same colony form, such as Bugula stolonifera and Bugula neritina. On the other hand, other species as Buskia socialis and Bowerbankia gracillima, previously considered rare species within the Lagoon, gained relative importance. |
