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.
THE NUMBERS
Side by side.
WHAT THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Common thresher is represented by reported to 7.6 m / 24.9 ft; Whitetip reef shark by reported to 2.13 m / 7 ft. Length comparisons can exaggerate body bulk because the tail is exceptionally long. The species is usually smaller than its reported maximum.
Bite evidence
Common thresher: Its hunting performance cannot be reduced to jaw force. 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
Much of its length is tail, which it uses to stun prey. Its slim body lets it hunt inside reef crevices.
