An earthworm is not a filter feeder. Marine animals that feed by passing nutrient-rich water through their gills are called filter feeders because their gills filter nutrients from the water and pass them into their intestines. An earthworm does not have gills and does not normally live in water. The earthworm's digestive system consists of a pharynx, esophagus, crop (food receptacle), gizzard (used for grinding swallowed earth), and a long, straight intestine.
