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; Shortfin mako by reported to about 4.45 m / 14.6 ft. Weight is a rounded comparison reference. Record length and mass do not necessarily describe the same individual.

Bite evidence

Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Shortfin mako: No directly comparable maximum bite-force estimate is used.

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. Speed is its signature; the biggest animals are unusual and hard to verify.
