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; Oceanic whitetip by reported to 4 m / 13 ft. Length is a recorded maximum; mass is a rounded adult reference. The comparison deliberately distinguishes the record from common size.

Bite evidence

Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings. Oceanic whitetip: A traceable, species-wide maximum is not available.

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. Most individuals are under 3 m even though larger records exist.
