Requiem sharks are a family of sharks known as Carcharhinidae, which includes over 50 species of sharks found in warm, shallow waters around the world. The family includes several well-known species, including tiger sharks, bull sharks, blacktip sharks, and sandbar sharks.

Requiem sharks are characterized by their streamlined bodies, five to six gill slits on the sides of their head, and a pointed snout. They are typically medium to large-sized sharks, with most species ranging from 3 to 10 feet in length.

Requiem sharks are known for their powerful jaws and sharp teeth, which they use to catch and eat a wide variety of prey, including fish, squid, crustaceans, and even other sharks. They are also known for their ability to migrate long distances and adapt to a variety of habitats, including coral reefs, estuaries, and open ocean.

Despite their importance to marine ecosystems, many species of requiem sharks are threatened by overfishing, habitat loss, and other human activities. Some species, such as the sandbar shark and the blacktip shark, have been classified as vulnerable or near threatened by the International Union for Conservation of Nature (IUCN).

Overall, requiem sharks are a diverse and ecologically important family of sharks that play a crucial role in maintaining the health and balance of marine ecosystems around the world.
