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; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Upper records are uncommon; most adults are lighter. Upper records vary by region and source.

Bite evidence

Blue shark: No comparable maximum is used. Sand tiger shark: A reliable comparable maximum was not found.

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 protruding teeth look dramatic, but appearance alone does not reveal bite force.
