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; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Weight is a rounded comparison reference. Upper records vary by region and source.

Bite evidence

Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Sand tiger shark: A reliable comparable maximum was not found.

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 protruding teeth look dramatic, but appearance alone does not reveal bite force.
