QUICK VERDICT

Tiger shark is about 1.79× longer by these reference values.

Tiger shark uses a 5.5 m upper reference, compared with 3.08 m for Nurse shark. Tiger shark's weight reference is about 8.2× 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.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Nurse shark is represented by recorded to 3.08 m / 10.1 ft; Tiger shark by largest specimens exceed 5.5 m / 18 ft. Length is a recorded maximum; mass is a rounded adult reference. Both values describe exceptional animals, not an average adult.

Bite evidence

Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings. Tiger shark: Popular figures are often repeated without a traceable species-level method.

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

A small mouth and powerful suction suit its bottom-feeding life. Its broad diet is real; an exact maximum bite number is not well established.
