Blacktip reef shark is about 1.00× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.
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; Cladoselache by about 1.8 m / 6 ft. Most individuals are under 1.6 m. Calling it a modern-style shark hides major evolutionary distance.
Bite evidence
Blacktip reef shark: No standardized maximum is used. Cladoselache: No usable maximum-force model exists.
Living versus extinct
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
Ecology changes the matchup
It is far smaller than the offshore giants people often picture. It was an early shark-like chondrichthyan with a streamlined body.
