WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Blue shark is represented by about 3.8 m / 12.5 ft; Tiger shark by largest specimens exceed 5.5 m / 18 ft. Upper records are uncommon; most adults are lighter. Both values describe exceptional animals, not an average adult.

Bite evidence

Blue shark: No comparable 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

Its long fins and slender build matter more than raw bulk. Its broad diet is real; an exact maximum bite number is not well established.
