filter-feeders

Aquatic particle collectors

Filter-feeders are animals that obtain food by straining particles from water.

Baleen whales, clams, and flamingos are filter-feeders—they pass water through specialized structures that trap plankton, algae, or small organisms while letting water flow through.

The oyster beds act as natural filter-feeders, cleaning the bay's water.
