Cladoselache is about 8.6× longer by these reference values.
Cladoselache uses a 1.8 m upper reference, compared with 0.21 m for Dwarf lanternshark. 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
Cladoselache is represented by about 1.8 m / 6 ft; Dwarf lanternshark by about 0.21 m / 8.3 in. Calling it a modern-style shark hides major evolutionary distance. Tiny sample sizes make the exact maximum provisional.
Bite evidence
Cladoselache: No usable maximum-force model exists. Dwarf lanternshark: No standardized maximum is available.
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 was an early shark-like chondrichthyan with a streamlined body. One of the smallest known sharks also produces light.
