NOAA Photo Library Image - r0021111

A bucket full of quahogs, Mercenaria mercenaria. Quahogs feed by filtering plankton from the water, pumping up to a gallon per hour or more, depending on temperature. This feeding activity helps to improve water quality and clarity in Narragansett Bay and is an important ecological link between the Bay's water column and its benthic, or bottom-dwelling community.
