Megamouth shark is about 2.4× longer by these reference values.
Megamouth shark uses a 7.1 m upper reference, compared with 3 m for Lemon shark. Megamouth shark's weight reference is about 4.9× 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
Lemon shark is represented by commonly to 3 m / 10 ft; Megamouth shark by reported to about 7.1 m / 23 ft. The values are upper-end figures, not a typical adult profile. Sparse specimens make a true maximum difficult to establish.
Bite evidence
Lemon shark: No standardized maximum is available for a fair cross-species comparison. 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
Decades of field research make this one of the best-studied coastal sharks. Known from relatively few encounters, it still carries major uncertainty.
