Megamouth shark is about 1.77× longer by these reference values.
Megamouth shark uses a 7.1 m upper reference, compared with 4 m for Bull shark. Megamouth shark's weight reference is about 3.8× 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.
THE NUMBERS
Side by side.
WHAT THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Bull shark is represented by reported to 4 m / 13 ft; Megamouth shark by reported to about 7.1 m / 23 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Sparse specimens make a true maximum difficult to establish.
Bite evidence
Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. Megamouth shark: This filter feeder lacks a comparable maximum-bite study.
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 freshwater range is exceptional among large coastal sharks. Known from relatively few encounters, it still carries major uncertainty.
