When people think of sharks, they generally imagine an animal like the one in this picture. The tall dorsal fin, torpedo-shaped body and giant teeth of this great white shark are familiar to most everybody. But there are actually more than 400 different shark species alive today, and they vary considerably in size and appearance. Anatomy. The first features that most people notice are their streamlined, torpedo-like shaped body, fins and sub terminal mouths (under their heads). A shark's body is adapted to living in the ocean, where every tail movement requires hard work to move through the dense medium. Many sharks need to keep swimming to breathe, so it is very. Sharks are fish, but their skeletons are made of cartilage, not bone. Shark ancestors did have bones, but these evolved to become cartilage, which made sharks lighter and more buoyant.. This diagram illustrates the main anatomical differences between sharks and bony fish. Anatomical differences differences between sharks and bony fish. Image Skeleton The skeleton of elasmobranchs is made of cartilage. Vestigial ribs give no support. The skeleton may be partially calcified to some extent with calcium phosphates and carbonates, particularly in the vertebral column. The calcified cartilage is not a true bone. The cartilage of a shark's skeleton may be important in future cancer research.

The diagram above does not represent any one species of shark, but rather is a compilation of the features posessed by many different species.

Overview What makes a shark a shark? What adaptations help them survive in their habitats? Students explore shark anatomy by becoming "experts" on shark adaptations and physical characteristics. They take part in a debate justifying the importance of their adaptation or characteristic and then do research to see how specific sharks compare. Label Me! Printouts.
