Carcharhinidae

Carcharhinidae is a large family of sharks, commonly known as requiem sharks. They are a diverse group with over 60 species found in tropical and warm-temperate oceans worldwide. These sharks are characterized by having two dorsal fins, an anal fin, five gill slits, and a nictitating membrane over their eyes. They are typically streamlined predators with a pointed snout and sharp teeth, adapted for catching a variety of prey including fish, squid, and crustaceans.

The family includes many well-known species such as the blacktip shark, bull shark, tiger shark, and oceanic whitetip shark. Their habitats vary widely, ranging from shallow coastal waters and coral reefs to the open ocean. Many carcharhinids are of commercial importance, being caught for their meat, fins, and liver oil. However, some species are considered vulnerable or endangered due to overfishing and habitat degradation. Their ecological role as apex or mesopredators is significant in maintaining the balance of marine ecosystems.
