Megamouth shark is about 3.5× longer by these reference values.
Megamouth shark uses a 7.1 m upper reference, compared with 2 m for Frilled shark. Megamouth shark's weight reference is about 81× 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
Frilled shark is represented by about 2 m / 6.6 ft; Megamouth shark by reported to about 7.1 m / 23 ft. Deepwater records remain limited. Sparse specimens make a true maximum difficult to establish.
Bite evidence
Frilled shark: No standardized maximum is available. 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 body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils. Known from relatively few encounters, it still carries major uncertainty.
