Etymology
The etymology of the name Physella is obscure but could be ultimately from a Greek root. "Physella" (as a place name) is recorded in Giovanni Gemisto's printed edition of Pliny's encyclopedia, perhaps lifted from Ermolao Barbaro's Castigationes Plinianae where it is recorded as Physcella.[3] The French naturalist Jacques Draparnaud was the first to describe a species of the genus Physella and coined the name.
Shell description
Snails in the family Physidae have shells that are sinistral, which means that if the shell is held with the aperture facing the observer and the spire pointing up, then the aperture is on the left-hand side.
The shells of Physella species have a long and large aperture, a pointed spire, and no operculum. The shells are thin and corneous and rather transparent.
Distribution
It was once thought that the indigenous distribution of Physella acuta is Mediterranean.[4][5] However, when Physella heterostropha is considered to be a synonym, then the indigenous distribution of the species includes North America.[6]
Physella acuta is a common species which is common in all of North America and Europe including the United Kingdom. The species seems to have first spread through the Mediterranean regions and then more slowly into Northern Europe.[2][6] This species has been introduced into New Zealand and is widespread throughout both islands in ponds, lakes, and running water [7]
In the United Kingdom
Within the United Kingdom, P. acuta is considered to be an invasive species. The "European Physa" or "common bladder snail", as it is commonly known in England, is a prolific species that has undergone naturalisation. The European Physa has been observed on several great Rivers, streams and tributaries within England, Wales, Scotland and Northern Ireland including the River Severn and the River Thames.[8] The ecological impact of this invasive species to the native floral and faunal species of the United Kingdom was assessed by the United Kingdom Technical Advisory Group (UKTAG) as "Unknown"[9] under the Water Framework Directive guidelines for Alien species.
In Europe
This species is found in:
- Belgium
- Serbia (it is especially abundant in the Drina river)
- Croatia
- Italy
- Czech Republic[10] – not evaluated (NE)[11]
- Slovakia[10]
- Germany[12]
- Netherlands[13]
- Denmark
and others
The distribution also includes
In the Americas
The distribution includes the United States: Maryland, New Jersey, Tennessee, and Virginia.[14]
- Cuba – native, also with Tarebia granifera it is the most common freshwater snail in Cuba[15]
- Chile invasive[16]

Ecology
Habitat
This species lives in freshwater rivers, streams, lakes, ponds, and swamps.[14]
Physella acuta is frequently found in anthropogenic reservoirs, occurring in warm water discharges from power stations and in some rivers, but very rarely and not numerously in clay pit ponds. It can survive well under temporary harsh conditions (extreme temperature and water pollution), as long as they are short-lived.[6]
Feeding habits
These snails eat dead plant and animal matter and various other detritus.
Because Physella acuta forages mainly on epiphytic vegetation and on the macrophytes, whereas other gastropods (
Interspecific relationship
This species successfully co-exists with other alien gastropods: for example with
Predators
The bladder snail is a frequent prey of many snail-eating predators, such as
- Anomalochromis
- Badis badis
- Carinotetraodon travancoricus
- Puntius titteya
- Ambastaia sidthimunki
- Chromobotia macracanthus
- Sternotherus carinatus
- Glossiphonia weberi [19][22]
Reproduction
P. acuta is a self-compatible
In the aquarium
P. acuta is one of a variety of snails often called "pest snails" in freshwater fishkeeping, due to their tendency to be introduced into tanks inadvertently via hitching a ride on ornamental plants unnoticed, combined with how readily and quickly they reproduce due in part to their ability to self-fertilize. Others will however intentionally keep bladder snails, as their diet and ease of care can prove to make them a useful part of a tank's clean-up crew.
