The Order Carcharhiniformes, also known as ground sharks, is the largest order of sharks, encompassing over 270 species, including requiem sharks, tiger sharks, and hammerheads. These sharks are characterized by a nictitating membrane over the eyes, two dorsal fins, an anal fin, and five gill slits. They inhabit a wide range of marine environments, from shallow coastal waters to the open ocean, and are mostly predatory, feeding on fish, cephalopods, and other marine animals. Carcharhiniformes display diverse reproductive strategies, including oviparity, viviparity, and placental viviparity, and play a critical role as apex and mesopredators in maintaining the balance of marine ecosystems.
