Oysters filter these pollutants, and either eat them or shape them into small packets that are deposited on the bottom where they are harmless. In Sweden, environmental agencies utilize mussel farming as a management tool in improving water quality conditions, where mussel bioextraction efforts have been evaluated and shown to be a highly effective source of fertilizer and animal feed[16] In the U.S., researchers are investigating potential to model the use of shellfish and seaweed for nutrient mitigation in certain areas of Long Island Sound.[17]. The whale shark sucks in a mouthful of water, closes its mouth and expels the water through its gills. That means a Whale sharks swims with their mouths open filtering out the water but keeping the food in, such as plankton. 1. As opposed to predators who seek out specialized food items, filter feeding is simply opening up your mouth and taking in whatever happens to be there, while filtering out the undesirable parts. Whale sharks are a type of carpet shark which are named so due to their carpet-like patterning. They are also a natural check to the deadly red tide. Scientists believe that the Chesapeake Bay's once-flourishing oyster population historically filtered the estuary's entire water volume of excess nutrients every three or four days. Can we bring a species back from the brink? [5] The basking shark is a passive filter feeder, filtering zooplankton, small fish, and invertebrates from up to 2,000 tons of water per hour.

The shark is unaffected as it's done eating anyway mutualism Ostrich/Gazelle: Ostriches and gazelles feed next to each other. Mussels open their shells and draw in food, filtering food particles over their gills, while clams use mucus on their gills to catch plankton as they push water in and out of their siphons [source: Chesapeake Quarterly]. This means that it opens its mouth and strains its food through a filtering structure. Of course, there must be a critical concentration of food particles in the water, or the filter feeder will starve. In bivalves such as the clam, the gills, larger than necessary for respiration, also function to strain . Their baleen plates are narrow and very long up to 4m (13ft) in bowheads and accommodated inside the enlarged lower lip which fits onto the bowed upper jaw. The whale shark, the largest shark, feeds on millions of tiny plankton in massive gulps, and is a favorite species recognizable by most. The motion is so slow that copepods cannot sense it and do not react with an escape response. Perhaps this shark represents one particular way to filter feed that evolved prior to the mass extinction at the end of the Cretaceous period that killed off roughly 75 percent of all marine species. The study also concluded they have soft fins ill-suited for swimming at speeds necessary for trapping krill and restricted gill openings that wouldnt allow enough water to flow out of its mouth while moving. The baleen whales (Mysticeti), one of two suborders of the Cetacea (whales, dolphins, and porpoises), are characterized by having baleen plates for filtering food from water, rather than teeth. Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Nearly all tunicates are suspension feeders, capturing planktonic particles by filtering sea water through their bodies. However, only Pterodaustro showcases a proper pumping mechanism, having up-turned jaws and powerful jaw and tongue musculature. An undulating live Aurelia in the Baltic Sea showing the grid in action. The basking shark feeds on zooplankton, small fish, copepods, and invertebrates in the water. Gentle giants, whale sharks filter-feed, swimming with their wide mouths open, collecting plankton and small fish. While other sharks may not feed in a comparable way, that does not mean it is completely novel in the marine world. Including the megamouth, there are three species of filter feeding sharksthe whale shark and the basking shark round out the bunch. The whale shark, like the world's second largest fish, the basking shark, is a filter feeder. Mysidacea are small crustaceans that live close to shore and hover above the sea floor, constantly collecting particles with their filter basket. When hauled up on deck in 1976, this megamouth became the first specimen viewed by people. The comparative roles of suspension-feeders in ecosystems. They tend to feed near the surface and often by the mouths of rivers, and will eat continuously around the clock. The whale shark, like the world's second largest fish, the basking shark, is a filter feeder. Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. The blue whale is a magnificent creature, but it looks like it has a permanent grin. Mussel farming as a nutrient reduction measure in the Baltic Sea: consideration of nutrient biogeochemical cycles. The crested horn shark is a type of bullhead shark, living off the coast of Australia. It is unique in being a large, flightless marine animal, unlike the smaller still volant flamingos and prions. Basking Sharks are passive feeders, meaning they take in water as they swim. The feeding anatomy, behavior and diet of the whale shark Rhincodon typus were studied off Cabo Catoche, Yucatan Peninsula, Mexico. A baleen is a row of a large number of keratin plates attached to the upper jaw with a composition similar to those in human hair or fingernails. They are an important food source for herring, cod, flounder, and striped bass. For example, the average harvested mussel contains: 0.81.2% nitrogen and 0.060.08% phosphorus[15] Removal of enhanced biomass can not only combat eutrophication and also support the local economy by providing product for animal feed or compost. Most forage fish are filter feeders. The coral spawning of the area's Ningaloo Reef provides the whale shark with an abundant supply of plankton. A primitive type of shark, the bluntnose sixgill is thought to date back to the Triassic period, when dinosaurs still walked the earth. Basking sharks can grow to be up to 30 feet long and weigh up to 5 tons! Though often found in the open water, they tend to stay near the surface of the water. Filter feeders can help clear water.

If an aquatic animal isn't a filter feeder, it has to be a bulk feeder or bottom feeder. Filter feeders engage in one of the four major types of feeding, the others being deposit feeding (eating particles in soil), fluid feeding (as in spiders and hummingbirds), and bulk feeding (as in humans and most other animals). They are useful as they are sessile, which means they are closely representative of the environment where they are sampled or placed (caging), and they breathe water all the time, exposing their gills and internal tissues: bioaccumulation. This distinguishes them from the other suborder of cetaceans, the toothed whales (Odontoceti). Basking sharks, another endangered filter feeder that can be mistaken for great whites, are also found off the Florida coast.
