Carcharhinidae, commonly known as the requiem sharks, is a family of sharks that includes many well-known species such as the blacktip shark and the bull shark. These sharks are typically characterized by their streamlined bodies, pointed snouts, and large dorsal fins. They are found in warm, shallow waters around the world, often near coastlines and in estuaries. Requiem sharks are known for their active hunting behavior and are primarily carnivorous, feeding on fish, crustaceans, and sometimes even other sharks. They play a crucial role in marine ecosystems as apex predators, helping to maintain the balance of marine life. Their populations are threatened by overfishing and habitat loss.
