Great hammerhead is about 1.52× longer by these reference values.
Great hammerhead uses a 6.1 m upper reference, compared with 4 m for Bull shark. Great hammerhead's weight reference is about 1.42× 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 SETS THEM APART
More than a size contest.
Length and weight
Bull shark is represented by reported to 4 m / 13 ft; Great hammerhead by reported to 6.1 m / 20 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. The comparison uses the largest reported length and a record mass.
Habitat and diet
Bull shark: Coasts, estuaries and freshwater; fish, rays, turtles and other sharks. Great hammerhead: Tropical coastal and offshore waters; rays, fish and smaller sharks.
Bite evidence
Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here.
Records are not averages
Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
