Greenland shark is about 11× longer by these reference values.
Greenland shark uses a 6.4 m upper reference, compared with 0.56 m for Cookiecutter shark. Greenland shark's weight reference is about 205× 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
Cookiecutter shark is represented by about 0.56 m / 22 in; Greenland shark by confirmed to about 6.4 m / 21 ft. Weight is a rounded comparison reference. Age and upper mass involve uncertainty; length is better documented.
Bite evidence
Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Greenland shark: TuffShark found no defensible species-level bite-force estimate to display.
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 bite removes a round plug; size alone does not predict ecological impact. The age estimate is extraordinary; a dependable bite-force figure is not available.
