Filter feeders (verb: filter feeding) is an animal that eats by sieving small food items from water. Many invertebrate filter feeders, such as bivalve molluscs and sea squirts, are sessile animals that collect food by pumping water through or across their bodies. Vertebrate filter feeders, such as baleen whales, collect their food by trapping it while they are on the move.
