Bull sharkvsShortfin mako

Length, weight and bite evidence—plus context from a human, city bus and blue whale. Every number below carries its uncertainty with it.

QUICK VERDICT

Shortfin mako is about 1.11× longer by these reference values.

Shortfin mako uses a 4.45 m upper reference, compared with 4 m for Bull shark. Shortfin mako's weight reference is about 1.80× 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

Bull shark is represented by reported to 4 m / 13 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Record length and mass do not necessarily describe the same individual.

Bite evidence

Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. Shortfin mako: No directly comparable maximum bite-force estimate 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 freshwater range is exceptional among large coastal sharks. Speed is its signature; the biggest animals are unusual and hard to verify.
