The megamouth is a deep-water species and rarely seen by humans. Goblin shark 11. We now know that the goofy appearance is partly due to how the shark feeds. [14] Nutrient removal by shellfish, which are then harvested from the system, has the potential to help address environmental issues including excess inputs of nutrients (eutrophication), low dissolved oxygen, reduced light availability and impacts on eelgrass, harmful algal blooms, and increases in incidence of paralytic shellfish poisoning (PSP). They are also important in bioaccumulation and, as a result, as indicator organisms. "Filter Feeding." Not much is known about the species aside from their feeding . [9] 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. [11] Baleen whales typically eat krill in polar or subpolar waters during summers, but can also take schooling fish, especially in the Northern Hemisphere. Greenland Shark. Bivalve shellfish recycle nutrients that enter waterways from human and agricultural sources. Water is drawn into the body through the inhalant buccal siphon by the action of cilia lining the gill slits. Great white sharks like fatty meals and will, therefore, consume sea lions or a seal. 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. What Is a Filter Feeder? Stomatosuchidae is a family of freshwater crocodylomorphs with rorqual-like jaws and minuscule teeth, and the unrelated Cenozoic Mourasuchus shares similar adaptations. Jennifer Kennedy, M.S., is an environmental educator specializing in marine life. [11] Rorquals such as the blue whale, in contrast, have smaller heads, are fast swimmers with short and broad baleen plates. Instead of relying on teeth, megamouths are filter feeders, meaning they sift out small plankton (like krill) from the water. "The Encyclopedia of Sharks."
