Populations are particularly well developed in wave-protected areas such as bays, estuaries or sheltered sides of wave-exposed islands. Commercial fisherman collecting quahog clams (Mercenaria mercenaria), physically disrupt surface-dwelling organisms and also kill large numbers of predatory gastropods, including the channeled whelk, Busycotypus canaliculatus, and the drilling moonsnails Neverita duplicata and Euspira heros, to protect hard clam stocks. Although eelgrass restoration by seed is often considered the most ideal method of restoratio due to time and cost efficiency, genetic diversity, low impact on the donor meadow and relative . Thus, Bivalvia is the only molluscan class characterized by the absence of a radula. SFGate.Com The Great Invaders Glen Martin, February 5, 2006 A new ecosystem is evolving in San Francisco Bay. The differential ability to follow chemical plumes in a range of flow velocities may cause these two species of whelks to forage more efficiently in different hydrodynamic environments. The preferred method of opening the shell depends on the species of whelk and may be classed as 'wedging' and 'chipping'. This review deals with the measurement of filtration rates in suspension feeding bivalves. 2010, Quinn et al.
