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; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Length comparisons can exaggerate body bulk because the tail is exceptionally long. Upper records vary by region and source.

Bite evidence

Common thresher: Its hunting performance cannot be reduced to jaw force. 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

Much of its length is tail, which it uses to stun prey. Its protruding teeth look dramatic, but appearance alone does not reveal bite force.
