Shark with the largest teeth relative to body size

The shark with the largest teeth relative to body size is the largetooth cookiecutter Isistius plutodus, named after the Egyptian goddess Isis, and measuring around 0.4 m (1 ft 4 in) in total length. However, its lower jaw's 19 triangular teeth with interlocking rectangular bases are proportionately huge, twice as large relative to this species' total body length as the great white shark's teeth are in relation to its own total body length.
