They are active filter feeders which means they either suction water into their mouths or they ram feed which means they swim forward forcing the water and food into their mouths. The whale shark sucks in a mouthful of water, closes its mouth and expels the water through its gills. How did this mountain lion reach an uninhabited island? Nearly all tunicates are suspension feeders, capturing planktonic particles by filtering sea water through their bodies. Some birds, such as flamingos and certain species of duck, are also filter feeders. For now, the life of the megamouth remains a mystery. When they feed, they open their massive mouths and slowly glide through the clouds of plankton as the gill rakers remove the tiny plankton from the water. Vol. But despite sharing a similar feeding strategy, the three are not closely related and it is likely that they each evolved filter feeding independently. Filter feeding is a method of aquatic feeding in which the animal takes in many small pieces of prey at one time.

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. Their population status or structure, physiology, behaviour,[18] or their content of certain elements or compounds can reveal the contamination status of any aquatic ecosystem. Manta rays can time their arrival at the spawning of large shoals of fish and feed on the free-floating eggs and sperm. A whale shark can filter over 1,500 gallons of water an hour.
