Parasitology 129(6):771-778. Fingernail clams, like most other bivalve molluscs, are filter feeders that remove suspended organic materials from water: algae, tiny planktonic animals, plant and animal detritus, and so on. 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. Malacologia 16: 421-455. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed.

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). responsibility for any errors, omissions, or positional accuracy, and therefore, there are no Fingernail clam From Wikipedia, the free encyclopedia Redirect page Jump to navigationJump to search Redirect to: Sphaeriidae To scientific name of a mollusc: This is a redirect from a Penttinen, O., J.

It has not been found in ponds, lagoons, bog ponds, swamps or other stagnant water, one source suggests that these habitats do not have sufficient current to oxygenate the water. They are native and can be quite abundant, providing food for a variety of animals and producing large accumulations of empty shells. The list of references for all nonindigenous occurrences of Musculium sp. Like other clams, fingernail clams have two mirror-image shells that are hinged together, and the shells are generally rounded to triangular.

In cases where there are fewer, but larger and better-equipped young, the expense to parents is great, but the payoff in the percentage of offspring that survive to adulthood is great as well (think of a pair of birds laboriously tending their nest, feeding their hatchlings, driving away predators and rivals, and so on).

When a fingernail clam relaxes, its shells open slightly to allow the two siphons (left) and foot (right) to protrude. Fingernail clams are filter feeders that remove suspended organic materials from water, so they tend to clarify the water. Seasonal variation of survival time in anoxic water and the glycogen content of Sphaerium corneum and Pisidium amnicum (Bivalvia, Pisidiidae). 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.
