Great hammerhead is about 1.98× longer by these reference values.
Great hammerhead uses a 6.1 m upper reference, compared with 3.08 m for Nurse shark. Great hammerhead's weight reference is about 4.1× 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
Great hammerhead is represented by reported to 6.1 m / 20 ft; Nurse shark by recorded to 3.08 m / 10.1 ft. The comparison uses the largest reported length and a record mass. Length is a recorded maximum; mass is a rounded adult reference.
Bite evidence
Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here. Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings.
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 wide head is a sensory platform, not just an unusual silhouette. A small mouth and powerful suction suit its bottom-feeding life.
