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; Lemon shark by commonly to 3 m / 10 ft. Weight is a rounded comparison reference. The values are upper-end figures, not a typical adult profile.

Bite evidence

Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Lemon shark: No standardized maximum is available for a fair cross-species comparison.

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. Decades of field research make this one of the best-studied coastal sharks.
