THE NUMBERS
Side by side.
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; Zebra shark by reported to 3.54 m / 11.6 ft. Most individuals are under 1.6 m. Its very long tail adds substantially to total length.
Bite evidence
Blacktip reef shark: No standardized maximum is used. Zebra 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. Juveniles have stripes; adults are spotted despite the common name.
