Sub-species level (?) | Not entered |
Native origin (?) | Ocean: Pacific --> Ocean region: SW Pacific References (not structured): Paavola M., A. Olenin, E. Leppakoski 2005. Are invasive species most successful in habitats of low native species richness across European brackish water seas? Estuarine, Coastal and Shelf Science, 64: 738-750. |
Life form / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: Branchiura sowerbyi are large, deep red, tubificid worms that are easily distinguished by the presence of dorsal and ventral gill pairs that cover the posterior quarter of the body. |
Sociability / Life stage (?) |

Reproductive frequency (?) | Not entered |
Reproductive type (?) | Asexual Sexual References: http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: Like other oligocheates, B. sowerbyi reproduces sexually via the clitellum and asexually through fragmentation. |
Developmental trait (?) | Brooding References: http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: May reach sexual maturity within 4 months with a breeding peak in the summer months of June through July. B. sowerbyi may display a one to two year life cycle, dependent upon temperature, dissolved oxygen and substrate organic content. |
Characteristic feeding method / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: These tubificid worms are benthic detritivores meaning that they live on the lake or river bottoms and feed from the decomposing organic matter in the sediment. |
Mobility / Life stage (?) |
References (not structured): http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=1151, Accessed 29 June 2012 Comments: As they feed, B. sowerbyi have been known to create intricate burrows up to 20 cm in depth. |
Salinity tolerance range (?) | Venice system: 1. Limnetic [<0.5psu] References: Paavola M, Olenin S, Leppäkoski E (2005) Are invasive species most successful in habitats of low native species richness across European brackish water seas? Estuarine, Coastal and Shelf Science 64 (2005) 738-750 |
