Hydrobia acuta neglecta is a European subspecies of small brackish water snail with a gill and an operculum, an aquatic gastropod mollusc in the family Hydrobiidae.Gofas, S. (2010). Hydrobia acuta neglecta Muus, 1963. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=465551 on 2010-05-05
Distribution
This species which has a distribution type: oceanic temperate occurs on the coasts of the North Sea, in countries and islands including: Iceland Denmark Sweden Great Britain Ireland France
Ecology Hydrobia acuta neglecta occurs in coastal lagoons where incoming freshwater dilutes sea water. The preferred salinity range is 10-24 ‰.Fretter, V. & Graham, A. (1978). "The prosobranch molluscs of Britain and Denmark. Part 3 – Neritacea, Viviparacea, Valvatacea, terrestrial and freshwater Littorinacea and Rissoacea". Journal of Molluscan Studies. Suppl. 5: 1-152.
Status The status of this taxon is uncertain. Hydrobia neglecta is treated as a full species in Fauna Europaea,Bank, R., von Proschwitz, T. & Falkner, G. (2006). Unpublished manuscript of the mollusca section of the Fauna Europaea web-site (https://fauna-eu.org). but in 1995 it had been suggested that H. neglecta is a synonym of the Mediterranean Hydrobia acuta (Draparnaud).Giusti, F., Manganelli, G. & Schembri, P. J. (1995). The Non-Marine Molluscs of the Maltese Islands. Monografie XV, Museo Regionale di Scienze Naturali, Torino. Then a neglecta colony in northern France was shown to be acuta.Hoeksema, D. F. (1998). "Note on the occurrence of Hydrobia acuta (Draparnaud, 1805) (Gastropoda, Prosobranchia: Hydrobiidae) in western Europe, with special reference to a record from S. Brittany, France". Basteria. 61: 101-113 In 2000 a molecular study concluded that north-west European populations were not specifically distinct from the Mediterranean Hydrobia acuta and designated them subspecies neglecta Muus.Wilke, T., Rolán, E. & Davis, G. M. (2000). "The mudsnail Genus Hydrobia s.s. in the northern Atlantic and western Mediterranean: a phylogenetic analysis". Marine Biology. 137: 827-833.
