QUICK VERDICT

White shark is about 2.8× longer by these reference values.

White shark uses a 6 m upper reference, compared with 2.13 m for Whitetip reef shark. White shark's weight reference is about 124× 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

White shark is represented by about 6 m / 20 ft; Whitetip reef shark by reported to 2.13 m / 7 ft. Maximum length and mass are exceptional upper-end figures. The species is usually smaller than its reported maximum.

Bite evidence

White shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark. Whitetip reef shark: No standardized maximum 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 headline bite number is a computer model, not a live-animal measurement. Its slim body lets it hunt inside reef crevices.
