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
Blacktip reef shark is represented by recorded to 1.8 m / 5.9 ft; Lemon shark by commonly to 3 m / 10 ft. Most individuals are under 1.6 m. The values are upper-end figures, not a typical adult profile.
Bite evidence
Blacktip reef shark: No standardized maximum is used. Lemon shark: No standardized maximum is available for a fair cross-species comparison.
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
It is far smaller than the offshore giants people often picture. Decades of field research make this one of the best-studied coastal sharks.
