Hydrobiologia 435:153-165. Fingernail clams, also called pill clams or pea clams, are members of a family of small to tiny freshwater clams that are common but rarely noticed. Like other clams, fingernail clams have two mirror-image shells that are hinged together, and the shells are generally rounded to triangular. Both genera have joined mantle rims extended to form long tube-shaped siphons (see pictures). In fingernail clams, the shells are thin and fragile, often translucent, the outsides typically shiny, fairly smooth, and gray, tan, yellowish, or whitish. It has also been recorded from ditches, marshes, puddles, muddy brooks, and larger lakes in Europe at an altitude of 1,300 to 1,400 m. In North America "it occurs in swamps, ponds, lakes, or streams on a firm bottom of fine deep or hard packed mud, fine gravel, and hard clay, in water up to 0.6 m deep; it has been collected in water with pH 6.4-7.64, fixed carbon dioxide ratio 9.3-18.87 ppm." Different species have different habitat preferences.

The many calcium-rich clam shells buffered the water, preventing it from becoming acidic, and preventing the dissolution of the egg fragments. States with nonindigenous occurrences, the earliest and latest observations in each state, and the tally and names of HUCs with observations. These shells can be quite fragile compared to introduced Asian clams of the family Corbiculidae, which have only been reported in Lake Elmo near Billings, Montana. Dispersal mechanisms good with records from maritimes to British Columbia and Northwest Territories. 1980. (Clarke 1981) indicates the species is common and occurs "principally in rivers and streams, but also occurs in large lakes and rarely, in small lakes. Effects of hypoxia on valve-closure time and bioaccumulation of 2,4,5-trichlorophenol by the Freshwater clam Sphaerium corneum [L.]. 1980, Mackie 2000, Peckarsky et al. Fingernail clams, also called pill clams or pea clams, are members of a family of small to tiny freshwater clams that are common but rarely noticed. Because these ponds lack fish (which would eat them), the eggs, tadpoles, and larval salamanders can grow to maturity in relative safety. 1777. 1987. They are native and can be quite abundant, providing food for a variety of animals and producing large accumulations of empty shells. Post the Definition of fingernail clam to Facebook, Share the Definition of fingernail clam on Twitter, Great Big List of Beautiful and Useless Words, Vol. It is native to the west coast of North America and its name is derived from the native american word meaning dig deep.

This seems to be the way these clams came to inhabit so many vernal pools long ago. Statewide. Pedal feeding from the bottom with the foot muscle has also been observed. (Clarke 1981).

Lepitzki, Robert Forsyth, http://ia902505.us.archive.org/3/items/malacologia131973inst/malacologia131973inst.pdf. Fingernail clams are mostly filter-feeders, siphoning in floating particulate organic materials ( small plant or animal) from the water column and straining out the particles and expel the strained water. are created to identify suitable habitat within their range and are not displayed on this map. The shell is covered in evenly spaced striae that become finer and fade out toward the beaks. These fascinating animals are related to fairy shrimp, water fleas, and tadpole shrimp. Bishop, M.J., and H. DeGaris. Observations in Montana Natural Heritage Program Database. Leach, J.T. It seems to prefer muddy bottoms. Like most other molluscs, fingernail clams are hermaphrodites: each individual can produce both eggs and sperm. Fingernail clams are small "mostly about the size of a finger or thumbnail" bottom-dwelling, filter-feeders found in ponds, lakes and streams throughout Montana.

Observations in Montana Natural Heritage Program Database, The species is found in a variety of habitats, including small lakes, rivers, creeks, trenches, canals, and sandy shoals. On the other hand, where the parental expenditure is low, but the numbers of offspring are many, mortality is high, but the odds of a few of them surviving to adulthood is also great (think of freshwater mussels broadcasting clouds of sperm and eggs into the water, and having little other parental investment beyond their bodies making and expelling the gametes). Missouri's streams, lakes, and other aquatic habitats hold thousands of kinds of invertebrates worms, freshwater mussels, snails, crayfish, insects, and other animals without backbones.
