Sub-species level (?) | Not entered |
Native origin (?) | Not known References (not structured): Wasson, B., De Blauwe, H. 2014. Two new records of cheilostome Bryozoa from British waters. Marine Biodiversity Records 7: e123. Comments: Fenestrulina delicia was discovered in Maine (United States) in 1994. Currently, this species occurs along the coast of France to Sweden. |
Life form / Life stage (?) |
|
Sociability / Life stage (?) |
Comments: Colonies of F. delicia have been found on both natural (such as algae) and artificial (such as dams) substrates. |
Reproductive frequency (?) | Not entered |
Reproductive type (?) | Asexual Sexual Comments: Bryozoans are hermaphrodites (androgynous). The larvae exhibit positive phototaxis and swim towards the light. Later in life, they exhibit negative phototaxis and swim to the bottom, where they attach themselves to a suitable substrate. Once attached at the bottom, chemical substances in the water determine whether it is a suitable spot to remain. If so, an adhesive material gets excreted, and the larva becomes an ancestrula that founds a new colony. The ancestrula originates from sexual reproduction, but the resulting colony is formed by asexual reproduction. Fenestrulinidae is a family of moss animals. Dead Fenestrulinidae form shallow marine sediments. They have sexual reproduction and asexual reproduction. |
Developmental trait (?) | Unknown |
Characteristic feeding method / Life stage (?) | Unknown Comments: As the lecitotrophic larvae of F. delicia do not feed in the plankton. |
Mobility / Life stage (?) |
Comments: F. delicia often grows attached to mussel shells. |
Salinity tolerance range (?) | Unknown References: López-Gappa, J., Liuzzi, M. G. 2016. High density of the alien bryozoan Fenestrulina delicia in the fouling assemblage of a South American harbour (Argentina). Marine Biodiversity, 46, pp. 509-513. Comments: It was found on experimental substrata submersed to study the fouling assemblage of Quequén Harbour (Argentina, southwest Atlantic), an estuarine environment.Mean values range from 6 to 27 PSU, while extreme salinity records may attain 4 and 32 PSU. pH values are always higher than 8, due to the absence of significant organic matter pollution. |
Habitat modifying ability potential (?) | Unknown |
Toxicity / Life stage (?) | Unknown Comments: Not available. |
Bioaccumulation association (?) | Unknown Comments: Not available. |
Known human health impact? | Not known Comments: Not available. |
Known economic impact? | Known References: López-Gappa, J., Liuzzi, M. G. 2016. High density of the alien bryozoan Fenestrulina delicia in the fouling assemblage of a South American harbour (Argentina). Marine Biodiversity, 46, pp. 509-513. Comments: Attachment of biofouling species (like F. delicia) to the hulls of ships can increase resistance when sailing. In turn, this increases fuel consumption, resulting in high economic costs. |
Known measurable environmental impact? | Not known Comments: Not available. |
