This footage, captured by @mattprior22 and @southwestrocksdive shows a sand tiger shark, also known as a grey nurse shark, detaching its jaws. Sharks are able to detach both their lower and upper jaws from their skull to help them catch prey. They have a high biting force due to the muscles that attach to the jaws, and typically kill their prey with strong head shaking once bitten. | OceanX | Facebook
