Environmental Pollution 117:523-530. 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. 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). For general information and questions about the database, contact Wesley Daniel.
