Gray whales live in shallow waters feeding primarily on bottom-living organisms such as amphipods.[11]. They are also important in bioaccumulation and, as a result, as indicator organisms. Basking sharks move water through their mouths by slowly swimming forward. "What Is a Filter Feeder?" Humans can eat up to half a ton. What is the largest animal in the world and it is a filter feeder? Combined with its lacustrine environment, it might have occupied a similar ecological niche. Baleen whales typically seek out a concentration of zooplakton, swim through it, either open-mouthed or gulping, and filter the prey from the water using their baleens. [28] Order Orectolobiformes (carpet sharks), Family Rhincodontidae (whale sharks) Share. Their mouths are lined with hundred of small, nonfunctional teeth in 50 rows. Its back and sides are gray to brown with white spots among pale vertical and horizontal stripes, and its belly is white. These large fish are also classed among the filter feeder sharks.

Baleen whales feed either by skimming the water and trapping prey on the fringe-like hairs of their baleen or gulping in large quantities of water and prey and then forcing the water out, leaving prey trapped inside. For example, the Atlantic menhaden, a type of herring, lives on plankton caught in midwater.
