The name "basking shark" comes from their habit of swimming near the surface of the water with their mouths open, filter-feeding on plankton. This fine sieve-like apparatus, which is a unique modification of the gill rakers, prevents the passage of anything but fluid out through the gills (anything above 2 to 3mm in diameter is trapped).

This is accomplished using cilia, which are thin filaments that beat to produce a current over water over the gills. 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. Bivalves filter-feed by straining organic matter from the water using their gills. The basking shark is a passive filter feeder, filtering zooplankton, small fish, and invertebrates from up to 2,000 tons of water per hour. For example, oysters draw water in over their gills through the beating of cilia. Filter feeding is a method of aquatic feeding in which the animal takes in many small pieces of prey at one time. As the right whale swims, a front gap between the two rows of baleen plates lets the water in together with the prey, while the baleens filter out the water.
