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

Oceanic whitetip is represented by reported to 4 m / 13 ft; Pacific sleeper shark by reported near 7 m / 23 ft. The comparison deliberately distinguishes the record from common size. Large values often depend on indirect or incomplete records.

Bite evidence

Oceanic whitetip: A traceable, species-wide maximum is not available. Pacific sleeper shark: No standardized maximum is 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

Most individuals are under 3 m even though larger records exist. Rare encounters make its maximum size less certain than familiar coastal species.
