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
Greenland shark is represented by confirmed to about 6.4 m / 21 ft; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Age and upper mass involve uncertainty; length is better documented. Upper records vary by region and source.
Bite evidence
Greenland shark: TuffShark found no defensible species-level bite-force estimate to display. Sand tiger shark: A reliable comparable maximum was not found.
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
The age estimate is extraordinary; a dependable bite-force figure is not available. Its protruding teeth look dramatic, but appearance alone does not reveal bite force.
