| Native origin (?) | Country: USA --> LME: 3. California Current References (not structured): Robertson A., 1905 – Non-incrusting Chilostomatous Bryozoa of the West Coast of North America. University of California Publications in Zoology 2(5): 235-322 (p. 266) Comments: from Southern California to Monterey Bay |

References (not structured): Dyrynda P.E.J. & Ryland J.S., 1982 – Reproductive strategies and life histories in the cheilostome marine bryozoans Chartella papyracea and Bugula flabellata – Mar. Biol. 71:241-256 Hayward P.J. & Ryland J.S., 1998 – Cheilostomatous Bryozoa. Part I. Aeteoidea-Cribrilinoidea - Synopses of the British Fauna (New Series) edited by Doris M. Kermack and R.S.K. Barnes – N° 10 (Second Edition). 366pp. Comments: B. neritina's life history may include an annual period of dormancy, in which colonies recede to a regenerative holdfast (Dyrynda & Ryland, 1982). |
| Sociability / Life stage (?) |

| Reproductive frequency (?) | Iteroparous References (not structured): Hayward P.J. & Ryland J.S., 1998 – Cheilostomatous Bryozoa. Part I. Aeteoidea-Cribrilinoidea - Synopses of the British Fauna (New Series) edited by Doris M. Kermack and R.S.K. Barnes – N° 10 (Second Edition). 366pp. |
| Reproductive type (?) | Asexual Sexual References: Hayward P.J. & Ryland J.S., 1998 – Cheilostomatous Bryozoa. Part I. Aeteoidea-Cribrilinoidea - Synopses of the British Fauna (New Series) edited by Doris M. Kermack and R.S.K. Barnes – N° 10 (Second Edition). 366pp. Comments: Hermaphroditic. Zooids release eggs around the middle of their lifespan, but don't release sperm until near the end, thus preventing self-fertilization. |
| Developmental trait (?) | Brooding Lecithotrophy References: Hayward P.J. & Ryland J.S., 1998 – Cheilostomatous Bryozoa. Part I. Aeteoidea-Cribrilinoidea - Synopses of the British Fauna (New Series) edited by Doris M. Kermack and R.S.K. Barnes – N° 10 (Second Edition). 366pp. Comments: The larvae settle within 2-10 hours, then metamorphose into the adult form. |
| Characteristic feeding method / Life stage (?) |

| Salinity tolerance range (?) | Exact range: 18 - 40 References: Kitamura, H., Hirayama, K. 1985. The Effect of Low Salinity on the Early Growth of a Bryozoan Bugula neritina in the Sea and Laboratory* 1, 2. Bulletin of the Japanese Society of Scientific Fisheries, 51(9), pp. 1401-1405. U.S. National Invasive Species Information Center. “Nemesis Species Summary: Branchiomma Luctuosum (Feather Duster Worm).” Invasions.si.edu, U.S. National Invasive Species Information Center, https://invasions.si.edu/nemesis/species_summary/-95. Accessed 5 Aug. 2024. Comments: Colonies repeatedly exposed to seawater lower than 20‰ will not grow to be a mature colony. If the seawater has a salinity higher than 25‰ they might grow to a mature stage and in salinities higher than 30‰ they grow well. |

| Known human health impact? | Known Comments: Harmless. |
| Known economic impact? | Known References: Davidson, S. K., Haygood, M. G. 1999. Identification of sibling species of the bryozoan Bugula neritina that produced different anticancer Bryostatins and harbor distinct strains of the bacterial symbiont "Candidatus endobugula sertula". Biological Bulletin, 196, pp. 273-280. Comments: B. neritina is a frequent fouling organism and has been found on fixed structures, ship hulls, in ships' internal water systems, and in power plants using seawater in warm waters worldwide. B. neritinahas a positive economic impact, as a source of bryostatins, potential anticancer compounds. |

Comments: B. neritina in subtropical-tropical waters worldwide is a major competitor in the fouling community. |

Can be also transported via tiny colonies attached to the sides of ballast tanks or on floating material inside the ballast tanks. Furthermore, it was found on sea chest samples |
