Sharks

Sharks are a diverse group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of their head, and pectoral fins that are not fused to the head. They are apex predators in many marine ecosystems, playing a crucial role in maintaining the balance of these environments. Known for their streamlined bodies, powerful jaws, and sharp teeth, sharks exhibit a wide range of sizes, from small, deep-sea species to the massive whale shark, the largest fish in the world. They inhabit a variety of habitats, from shallow coastal waters to the deep ocean.
