Sharks, found in deep and shallow waters throughout the oceans, are some of the oldest living creatures on planet Earth. Shark skeletons, made of rubbery tissue called cartilage, have fascinated scientists for eons. Sharks swim at high speeds under deep water, and their skeletons experience high pressure and strain. These swimming-induced loads are borne by the centrum—mineralized bony tissue present in the shark’s vertebrae. However, from a functional standpoint, it is not fully clear how the complex 3D mineral structures of the shark centrum support and distribute loads within it.
