Physidae Physidae, common name the bladder snails, is a monophyletic taxonomic family of small air-breathing freshwater snails, aquatic pulmonate gastropod molluscs in the clade Hygrophila.
Physidae The two established subfamilies are divided into seven new tribes including 11 new genera.
Physidae They have been used in studies of ecophenotypic plasticity, a so-called phenoplastic switch. Burt Vaughan of Washington State University indicates several studies in M. J. West-Eberhardt's recent compendium of research, "Developmental Plasticity & Evolution" (Oxford Press, 2003, pp. 307–362). A typical example involved rearing Physa gyrina, or Physa heterostropha in controlled pair groups in either water in which crayfish co-existed or water in which only fish co-existed. Within a month, differences in shell morphology appeared; i.e., snails exposed to shell-crushing fish predators showed wide apertures and very much strengthened, rotund shells. Snails exposed to crayfish only showed narrow-apertured, thin elongate shells, with barricading teeth.
Physidae The differences in the group have led to the creation of more than 23 genera, four grades and four clades within the family.
Physidae In 1921, the strong reaction of "Physa" to contact with leeches was first observed, and later studies have also been made. The observations are restricted to Physa fontinalis, an indigenous species to areas with indigenous predatory leeches, and Haitia acuta, introduced in Germany and the Netherlands. When "Physa" contacts another snail, either "Physa" or some other kind, the reaction is a rapid twisting of the shell back and forth to dislodge the other. The muscle used is the "physid muscle", not found in other Hygrophila, which therefore do not show this reaction. The leech-avoidance reaction carries the action one step further: on contact with a leech the snail twists its shell violently and detaches its foot from the substratum as well.
