Bull shark is about 1.30× longer by these reference values.
Bull shark uses a 4 m upper reference, compared with 3.08 m for Nurse shark. Bull shark's weight reference is about 2.9× 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
Bull shark is represented by reported to 4 m / 13 ft; Nurse shark by recorded to 3.08 m / 10.1 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Length is a recorded maximum; mass is a rounded adult reference.
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. 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 freshwater range is exceptional among large coastal sharks. A small mouth and powerful suction suit its bottom-feeding life.
