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

Goblin shark is represented by photo-based estimates to 5.4–6.17 m / 18–20 ft; Nurse shark by recorded to 3.08 m / 10.1 ft. The longest figures come from regression estimates based on photographs. Length is a recorded maximum; mass is a rounded adult reference.

Bite evidence

Goblin shark: Jaw speed and protrusion are not the same measurement as bite force. Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings.

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 jaws shoot forward rapidly; maximum body size remains uncertain. A small mouth and powerful suction suit its bottom-feeding life.
