QUICK VERDICT

Basking shark is about 5.6× longer by these reference values.

Basking shark uses a 12 m upper reference, compared with 2.13 m for Whitetip reef shark. Basking shark's weight reference is about 328× 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; Whitetip reef shark by reported to 2.13 m / 7 ft. The upper length is exceptional; the mass is a rounded comparison estimate. The species is usually smaller than its reported maximum.

Bite evidence

Basking shark: A comparable maximum-bite study is not available for this filter feeder. Whitetip reef shark: No standardized maximum 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. Its slim body lets it hunt inside reef crevices.
