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.
