QUICK VERDICT

Shortfin mako is about 3.6× longer by these reference values.

Shortfin mako uses a 4.45 m upper reference, compared with 1.22 m for Horn shark. Shortfin mako's weight reference is about 57× 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

Horn shark is represented by reported to 1.22 m / 4 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. Weight is a rounded adult reference. Record length and mass do not necessarily describe the same individual.

Bite evidence

Horn shark: Experiments also measured bites; the displayed range is the study's theoretical maximum from front to rear teeth. 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 rear teeth crush hard prey, and its bite mechanics have been tested directly and modeled. Speed is its signature; the biggest animals are unusual and hard to verify.
