Virginia Fringed Mountain Snail [Polygyriscus virginianus]
The Virginia fringed mountain snail has a tiny shell that measures only 4.5 millimeters (.18 in) in diameter. It has four to five whorls that increase in thickness toward the rim and have eight to ten spiral, comb-like fringes that occur inside the lower spiral grooves. The living animal inside the shell is white, without pigmented eyestalks, and is probably blind.
The Virginia fringed mountain snail is the only species in its genus and is considered to be amongst the rarest snails in North America. Very little is known about this snail other than it is a burrower and does not come to the surface except during extremely wet weather. Its habitat is along a steep river bank that is dominated by pine and oak scrub and honeysuckle, is relatively free of leaf litter, and has permanently damp soil.
This snail has been found only at a single site in Pulaski County, Virginia on the north bank of the New River. The exact size of the population is unknown but only 30 snails have ever been found alive. Habitat disturbance could harm this extremely rare species such as construction, chemicals, and reactivation of an old quarry adjacent to the habitat. Measures are being taken to protect its habitat but the Fish and Wildlife Service (FWS) recommends that additional research is need to aid recovery efforts.
