SHARK VS SHARK

Cookiecutter sharkvsWhite shark

Length, weight and bite evidence—plus context from a human, city bus and blue whale. Every number below carries its uncertainty with it.

QUICK VERDICT

White shark is about 11× longer by these reference values.

White shark uses a 6 m upper reference, compared with 0.56 m for Cookiecutter shark. White shark's weight reference is about 454× heavier.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Cookiecutter shark is represented by about 0.56 m / 22 in; White shark by about 6 m / 20 ft. Weight is a rounded comparison reference. Maximum length and mass are exceptional upper-end figures.

Bite evidence

Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. White shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark.

Living versus extinct

Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.

Ecology changes the matchup

Its bite removes a round plug; size alone does not predict ecological impact. Its headline bite number is a computer model, not a live-animal measurement.
