QUICK VERDICT

Basking shark is about 2.7× longer by these reference values.

Basking shark uses a 12 m upper reference, compared with 4.45 m for Shortfin mako. Basking shark's weight reference is about 11× 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

Basking shark is represented by reported to 12 m / 40 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. The upper length is exceptional; the mass is a rounded comparison estimate. Record length and mass do not necessarily describe the same individual.

Bite evidence

Basking shark: A comparable maximum-bite study is not available for this filter feeder. 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 enormous mouth strains plankton; it is not built for a giant predatory bite. Speed is its signature; the biggest animals are unusual and hard to verify.
