QUICK VERDICT

Whale shark is about 2.0× longer by these reference values.

Whale shark uses a 12.2 m upper reference, compared with 6.1 m for Great hammerhead. Whale shark's weight reference is about 47× 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

Great hammerhead is represented by reported to 6.1 m / 20 ft; Whale shark by well documented near 12.2 m / 40 ft. The comparison uses the largest reported length and a record mass. Exceptional historical lengths exist, but 12.2 m is a conservative comparison value.

Bite evidence

Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here. Whale shark: Whale sharks filter feed; a comparable maximum bite-force study is not available.

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 wide head is a sensory platform, not just an unusual silhouette. The largest living fish is a filter feeder, so a predatory bite ranking would mislead.
