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; Epaulette shark by reported to 1.07 m / 3.5 ft. Most individuals are under 1.6 m. Mass varies strongly with size and is shown only as a reference.

Bite evidence

Blacktip reef shark: No standardized maximum is used. Epaulette shark: No standardized maximum is used.

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. It can use its fins to walk across reef flats and tolerate low oxygen.
