Shark Teeth and Their Functions

Jonathan Bird explains the diversity of shark teeth, highlighting how different species have evolved teeth suited to their diets. Sharks feeding on invertebrates have flat teeth for crushing, while those eating fish have pointy teeth for gripping. Larger prey requires saw-shaped teeth, as seen in species like the Great White.
