Megamouth shark is about 2.0× longer by these reference values.
Megamouth shark uses a 7.1 m upper reference, compared with 3.54 m for Zebra shark. Megamouth shark's weight reference is about 35× 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
Megamouth shark is represented by reported to about 7.1 m / 23 ft; Zebra shark by reported to 3.54 m / 11.6 ft. Sparse specimens make a true maximum difficult to establish. Its very long tail adds substantially to total length.
Bite evidence
Megamouth shark: This filter feeder lacks a comparable maximum-bite study. Zebra 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
Known from relatively few encounters, it still carries major uncertainty. Juveniles have stripes; adults are spotted despite the common name.
