Elasmobranchii is a class of cartilaginous fish that includes sharks, rays, and skates, and are found in all oceans around the world and range from small to large sizes. Elasmobranchs have several unique features that distinguish them from other fish, including a skeleton made of cartilage rather than bone, multiple gill openings on each side of their head, and five to seven pairs of gill slits. They also have an electric sense organ called the ampullae of Lorenzini which helps them detect prey in dark or murky waters. Elasmobranchs are carnivorous predators that feed on smaller fish and invertebrates such as squid and crustaceans. Some species are also filter feeders, using their specialized mouths to strain plankton from the water column. Elasmobranchs play an important role in marine ecosystems by controlling populations of prey species and providing food for larger predators like seals and whales. Conservation efforts for elasmobranchs focus on protecting habitats such as coral reefs where they live as well as reducing fishing pressures that can lead to overfishing or bycatch mortality.
