This marginal marine/freshwater species is found in the eastern Mediterranean within the littoral zone. The detail of the current distribution is uncertain, as its differentiation from the closely related taxon, P. globularis (=P. littorina della Chiaje), has lead to confusion in the distribution records for these two species. However it is likely to be present within suitable habitats across the region, and hence although it could be considered Data Deficient, the likely EOO of the more restricted range for this species suggests that a listing of Least Concern is more appropriate.

Geographic Range [top]

Range Description:This identity of the species, and its differentiation from the closely related taxon, P. globularis (=P. littorina della Chiaje), has lead to confusion in the distribution records for these two species. Within Europe, according to World Checklist of Marine Species (WORMS), this species is now only found in Greece, however in the past it was recorded from the littoral zone in France, Spain (Balearics) and Italy. In France it was previously recorded from two sites, one in Pyrennees-Orientale region and Bouche de Rhone (Falkner et al. 2002). 

Elsewhere in the eastern Mediterranean (Italy to Greece) may be confused with P. globularis, and further research is needed on these two taxa. Most authors still consider that there are two valid taxa (P. globularis and P. sicana), one with a large apical whorl and the other with a smaller apical whorl. There are records of shells collected from Aegean and Mediterranean coasts of Turkey that have been identified as P. littorina (Demir, 2003), whereas the records from Israel are P. sicana.

In general, the eastern Mediterranean coastline, from Greece to Israel, is likely to be the main range for the species.

Habitat and Ecology [top]

Habitat and Ecology:In marginal transitional habitats along the shoreline, usually at hide tide level, in crevices, under stones.

Use and Trade [top]

Use and Trade: This species is not used nor traded.

Threats [top]

Major Threat(s): The species lives in marginal habitats right on the edge of the marine realm, and hence suffers from disturbance from coastal developments as well as oil pollution and other forms of pollution that reside on the surface of water bodies.

Conservation Actions [top]

Conservation Actions: There are no known conservation actions in place for this species and the urgent requirement is for a better understanding of the range and taxonomic status of the species.
