The shells of Physella species have a long and large aperture, a pointed spire, and no operculum. The etymology of the name Physella is obscure but could be ultimately from a Greek root. So they are not all bad. These snails eat dead plant and animal matter and various other detritus. Major Group: Gastropoda Order: Hygrophila Family: PhysidaeGenus: Physa (may be recorded as Physella)Species: acuta This family is represented in Asutralian freshwaters by a single species, Physa acuta Draparnaud. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Behav. Physella acuta is a species of small, left-handed or sinistral, air-breathing freshwater snail, an aquatic gastropod mollusk in the family Physidae.

Because Physella acuta forages mainly on epiphytic vegetation and on the macrophytes, whereas other gastropods (Planorbis planorbis, Radix ovata) exploit the algal cover or phytobentos on the bottom, competition between Physella acuta and other gastropods appears to be minimal. Physa acuta is a globally invasive freshwater snail native to North America. It was once thought that the indigenous distribution of Physella acuta is Mediterranean. The life span was 403 days with an overall growth rate of 0.2 mm/week. The embryo, juvenile, half- and full-life-cycle toxicity tests performed with the snail Physella acuta at different concentrations (0.06–0.5 or 1.0 mg L −1) of the model fungicide pyrimethanil at 15, 20 and 25 °C revealed, that pyrimethanil caused concentration-dependent effects at all test temperatures. The life span was 193 days with an increased overall growth rate of 0.4 mm/week. It is generally found amongst vegetation.Feeding ecology: Physa acuta is a scraper feeding on green algae, macrophytes and diatoms.Habit:Life history: Physa acuta snails are hermaphrodites capable of self-fertilisation. Mga kasarigan. Genus Physella Haldeman, 1842 (Type species Physa globosa Haldeman, 1842) (Synonyms Haitia Clench & Aguayo, 1932 (Type species: Physa (Haitia) elegans Clench & Aguayo, 1932). Physella heterostropha (Say, 1817)[3] Physella acuta (Acute Bladder Snail) is a species of Gastropoda in the family Bladder Snails.They are associated with freshwater habitat.Dead Acute Bladder Snail form shallow marine sediment s. Individuals can grow to 9 mm. other gastropods appears to be minimal. 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. "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. Using the changes in the shell length and the body weight of the snails as surrogate, the population growth of the snails was estimated along with longevity and the fecundity schedule. [4] The French naturalist Jacques Draparnaud was the first to describe a species of the genus Physella and coined the name. Terminology Images, Major Groups | Gastropoda (snails) | Hygrophila (snails) | Physidae. A. The life span is seven to twelve months. Physella integra (Haldeman, 1841)[3] This species lives in freshwater rivers, streams, lakes, ponds, and swamps. Draparnaud J - P - R. 1805 … Eggs become embryonated in freshwater over ~2 weeks ; embryonated eggs release miracidia, which invade a suitable snail intermediate host. Physella acuta bladder snails.

However, gastropods offer some relevant models, especially among freshwater hermaphrodites, such as Physa acuta or Biomphalaria glabrata, easy to breed, with decent generation times (6–8 weeks) and improving genomic resources. Physella acuta has the standard metazoan complement of mt genes consisting of 13 protein-encoding genes, 2 ribosomal RNA (rRNA) genes and 22 transfer RNA (tRNA) genes.

It's PHYSELLA ACUTA, which goes by many names, including Tadpole Snail, Bladder Snail, Left-handed Pond Snail, Pewter Physa and Protean Physa. Physella acuta (Draparnaud, 1805) [7], Physella acuta is a common species which is common in all of North America and Europe. Maybe the Tadpole name arises from the fact that some tadpoles bear spots like this snail's shell. Physa acuta is the most common and widespread freshwater gastropod inhabiting our entire 14-state study area, a title it could probably claim for North America, and quite possibly the world (Dillon et al., 2002).
