Sharks possess several unique internal structures, including a cartilaginous skeleton, which is lighter and more flexible than bone. They have a highly developed nervous system, including a large brain relative to body size, and specialized sensory organs like the ampullae of Lorenzini for detecting electrical fields. Their digestive system features a spiral valve intestine, which increases nutrient absorption, and they have multiple rows of replaceable teeth. Additionally, sharks have a unique system of buoyancy regulation by using oil-filled livers, allowing them to maintain depth without expending energy.
