Herrington served his church for 44 years in 10 pastoral Table 1. Sphaeriidae (a family of small freshwater clams) in class Bivalvia (bivalve molluscs) 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. It also means that they are an early step in aquatic food webs, since they consume tiny suspended algae and other foods and convert it to the form of their bodies. 1777. 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). They were not fished commercially, but an eager asian market has developed. Species distribution models Museum of Zoology, University of Michigan, Miscellaneous Publications 118. EOL has data for 5 attributes, including: Known occurrences, collected specimens and observations of Grooved Fingernail Clam. WebKey Characteristics. 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). Borchert, J., L. Karbe, and J. Westendorf. Watson, A.M., and S.J. Biologists point out that there are tradeoffs between producing rather large, well-developed young in relatively small numbers, versus tiny, undeveloped young in masses: In the animal kingdom, both strategies can be effective.
