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.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Cookiecutter shark is represented by about 0.56 m / 22 in; Goblin shark by photo-based estimates to 5.4–6.17 m / 18–20 ft. Weight is a rounded comparison reference. The longest figures come from regression estimates based on photographs.

Bite evidence

Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Goblin shark: Jaw speed and protrusion are not the same measurement as bite force.

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 bite removes a round plug; size alone does not predict ecological impact. Its jaws shoot forward rapidly; maximum body size remains uncertain.
