QUICK VERDICT

Basking shark is about 1.97× longer by these reference values.

Basking shark uses a 12 m upper reference, compared with 6.1 m for Great hammerhead. Basking shark's weight reference is about 13× 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; Great hammerhead by reported to 6.1 m / 20 ft. The upper length is exceptional; the mass is a rounded comparison estimate. The comparison uses the largest reported length and a record mass.

Bite evidence

Basking shark: A comparable maximum-bite study is not available for this filter feeder. Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here.

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. Its wide head is a sensory platform, not just an unusual silhouette.
