In this case, that includes comparing the anatomy of the available specimens to the anatomy of other filter feeders. In Sweden, environmental agencies utilize mussel farming as a management tool in improving water quality conditions, where mussel bioextraction efforts have been evaluated and shown to be a highly effective source of fertilizer and animal feed[16] In the U.S., researchers are investigating potential to model the use of shellfish and seaweed for nutrient mitigation in certain areas of Long Island Sound.[17].

Scientists believe that the Chesapeake Bay's once-flourishing oyster population historically filtered the estuary's entire water volume of excess nutrients every three or four days. This is accomplished through filter feeding, using the krill's developed front legs, providing for a very efficient filtering apparatus: the six thoracopods form a very effective "feeding basket" used to collect phytoplankton from the open water.

I did not realize that so many different species were filter feeders, or that sometimes one filter feeder may eat another. Porcelain crabs have feeding appendages covered with setae to filter food particles from the flowing water. The Basking Shark is a passive filter-feeder, relying on ram-jet ventilation to force plankton-bearing water through its pharynx and out the gills. However, because Leuconia has more than 2 million flagellated chambers whose combined diameter is much greater than that of the canals, water flow through chambers slows to 3.6cm per hour. Basking sharks and whale sharks feed by swimming through the water with their mouths open.
