So how do they do it? The whale shark's flattened head sports a blunt snout above its mouth with short barbels protruding from its nostrils. During the slight delay between closing the mouth and opening the gill flaps, plankton is trapped against the dermal denticles which line its gill plates and pharynx. 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. Instead of relying on teeth, megamouths are filter feeders, meaning they sift out small plankton (like krill) from the water. How do leopards kill animals larger than they are? Whale shark 5. Whale sharks and basking sharks start out looking relatively normal and then when they feed their face opens up to form a gigantic strainer.

All baleen whales except the gray whale feed near the water surface, rarely diving deeper than 100m (330ft) or for extended periods. Water is expelled through a single osculum at a velocity of about 8.5cm/second: a jet force capable of carrying waste products some distance away from the sponge. The whale shark forages for food at or near the surface of the ocean. Manta rays can time their arrival at the spawning of large shoals of fish and feed on the free-floating eggs and sperm. Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. Some filter feeders, like certain whales, may feed on other filter feeders. Preferring warm waters, whale sharks populate all tropical seas. Eventually you'd recover from your bout of laziness to grill up a fat, juicy steak or at least order a cheesy pizza.

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. Though they are all large, docile creatures that feed on small plankton, they each have unique characteristics to their species. In the absence of an observation of the megamouth feeding, scientists turn to the next best thing. The largest megamouth shark ever caught was 25 feet long, but researchers believe megamouth sharks grow up to 16 feet long. A clam is a filter feeder. Basking Sharks differ from Whale Sharks in their feeding behaviors as well. Its two dorsal fins are set rearward on its body, which ends in a large dual-lobbed caudal fin (or tail). For example, whale sharks and baleen whales are both filter feeders. This is accomplished through filter feeding, using the krill's developed front legs, providing for a very efficient filtering apparatus:[8] the six thoracopods form a very effective "feeding basket" used to collect phytoplankton from the open water. The name "basking shark" comes from their habit of swimming near the surface of the water with their mouths open, filter-feeding on plankton. Leuconia, for example, is a small leuconoid sponge about 10cm tall and 1cm in diameter. Their oddly shaped beaks are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The Basking Shark is a passive filter-feeder, relying on ram-jet ventilation to force plankton-bearing water through its pharynx and out the gills. Gray whales live in shallow waters feeding primarily on bottom-living organisms such as amphipods. Engineer Graham Wilhelm joined National Geographic Emerging Explorer Brad Norman on an expedition to Ningaloo Reef, Australias longest fringing reef. This allows them to consume close to 150 gallons of water in one gulpthe amount of water held by two standard bath tubs. ThoughtCo.

The mouth of the Megamouth Shark is uniquely designed to attract unsuspecting prey. A few types of whales are filter feeders. Its possible megamouths do something similar, engulfing their prey and then slowly releasing the water out through their gills. Usually when you see something on TV about filter feeders in the ocean, this they seem to focus on whales, especially the big ones like blue whales. Sponges have no true circulatory system; instead, they create a water current which is used for circulation. In bivalves such as the clam, the gills, larger than necessary for respiration, also function to strain . Another of the ocean's giant filter-feeders, the megamouth shark reaches lengths of between 13 to 16 feet. 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. Small fish are also part of the Whale Shark diet, but they will only feed on them when plankton is sparse. (May 5, 2008)http://montereybay.noaa.gov/research/techreports/ucsc/crolltershytr.pdf, "Feeding Behavior."

[citation needed], Tunicates, such as ascidians, salps and sea squirts, are chordates which form a sister group to the vertebrates. As the right whale swims, a front gap between the two rows of baleen plates lets the water in together with the prey, while the baleens filter out the water. Basking Sharks swim at roughly 2.3 mph with their mouths open and gill rakers erect and take in up to 2,000 tons of water in an hour. Nephridia, the shell fish version of kidneys, remove the waste material. The Megamouth Sharks mouth is surrounded by bioluminescent organs called photophores that illuminate. Basking sharks and whale sharks feed by swimming through the water with their mouths open.
