Goblin shark is about 3.4× longer by these reference values.
Goblin shark uses a 6.17 m upper reference, compared with 1.8 m for Cladoselache. 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; Goblin shark by photo-based estimates to 5.4–6.17 m / 18–20 ft. Calling it a modern-style shark hides major evolutionary distance. The longest figures come from regression estimates based on photographs.
Bite evidence
Cladoselache: No usable maximum-force model exists. Goblin shark: Jaw speed and protrusion are not the same measurement as bite force.
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. Its jaws shoot forward rapidly; maximum body size remains uncertain.
