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; Tiger shark by largest specimens exceed 5.5 m / 18 ft. Most individuals are under 1.6 m. Both values describe exceptional animals, not an average adult.

Bite evidence

Blacktip reef shark: No standardized maximum is used. Tiger shark: Popular figures are often repeated without a traceable species-level method.

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. Its broad diet is real; an exact maximum bite number is not well established.
