WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Great hammerhead is represented by reported to 6.1 m / 20 ft; Whitetip reef shark by reported to 2.13 m / 7 ft. The comparison uses the largest reported length and a record mass. The species is usually smaller than its reported maximum.

Bite evidence

Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here. Whitetip reef 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

Its wide head is a sensory platform, not just an unusual silhouette. Its slim body lets it hunt inside reef crevices.
