They are also important in bioaccumulation and, as a result, as indicator organisms. The whale shark's flattened head sports a blunt snout above its mouth with short barbels protruding from its nostrils. When schools of little fish are hard to find, the large fish can endure a little starvation, as they swim farther and longer to find more food. New York, NY: Facts on File. Additional cilia remove the food. The feeding anatomy, behavior and diet of the whale shark Rhincodon typus were studied off Cabo Catoche, Yucatan Peninsula, Mexico. They scoop these tiny plants and animals up, along with any small fish that happen to be around, with their colossal gaping mouths while swimming close to the water's surface. A slow-moving filter feeder, its common name derives from its habit of feeding at the surface, appearing to be basking in the warmer water there. Because a blue whale is the largest living animal, maybe even the largest animal that has ever lived, and it eats other animals for food using filter feeding, the blue whale is considered the largest living omnivore. 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. Sperm whales and cookiecutter sharks are among the animals that live in its waters. Whale sharks have been observed "coughing" and it is presumed that this is a method of clearing a build up of food particles in the gill rakers. Water is drawn into the body through the inhalant buccal siphon by the action of cilia lining the gill slits. 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. This distinguishes them from the other suborder of cetaceans, the toothed whales (Odontoceti). For example, whale sharks and baleen whales are both filter feeders. They tend to feed near the surface and often by the mouths of rivers, and will eat continuously around the clock.

Unlike the megamouth and whale sharks, the basking shark does not appear to actively seek its quarry; but it does possess large olfactory bulbs that may guide it in the right direction. As with many shark species, the females are larger than the males and can get up to 18 feet long. Filter feeding is a method of aquatic feeding in which the animal takes in many small pieces of prey at one time. Inside their mouths are 300-350 tiny teeth and 10 filter pads. Suspended food (phytoplankton, zooplankton, algae and other water-borne nutrients and particles) are trapped in the mucus of a gill, and from there are transported to the mouth, where they are eaten, digested and expelled as feces or pseudofeces. 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. These sharks are found all over the globe and are incredibly fascinating examples of shark species. Filter feeding is a method of aquatic feeding in which the animal takes in many small pieces of prey at one time. Sharks that filter feed have tiny teeth that line their mouth and help to strain the plankton before the water exits their gill slits in other words, they don't use their teeth to grab prey.

Species like blue and humpback whales engulf their prey in gigantic gulps and then slowly sift the water back out through their baleen. 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). Like Basking Sharks they are passive filter feeders. 2008. On the sides of their heads, just behind their mouths they have two small eyes and two spiracles, small gill slits used to breath.

Filter feeding is found primarily among the small- to medium-sized invertebrates but occurs in a few large vertebrates (e.g., flamingos, baleen whales). In lower food concentrations, the feeding basket is pushed through the water for over half a meter in an opened position, and then the algae are combed to the mouth opening with special setae on the inner side of the thoracopods. They are known to migrate every spring to the continental shelf of the central west coast of Australia. 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. Flamingos filter-feed on brine shrimp. It is estimated that water enters through more than 80,000 incurrent canals at a speed of 6cm per minute. 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. Gentle giants, whale sharks filter-feed, swimming with their wide mouths open, collecting plankton and small fish. Bivalve shellfish recycle nutrients that enter waterways from human and agricultural sources. Filter feeding is a popular feeding mode among aquatic organisms because it requires little active effort: just float around and let the food particles come to you. A few types of whales are filter feeders. In lower food concentrations, the feeding basket is pushed through the water for over half a meter in an opened position, and then the algae are combed to the mouth opening with special setae on the inner side of the thoracopods. The largest shark species in the world ironically eat the smallest animals. Megamouth sharks live far offshore and likely spend much of their time deep underwater.
