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
Dwarf lanternshark is represented by about 0.21 m / 8.3 in; Nurse shark by recorded to 3.08 m / 10.1 ft. Tiny sample sizes make the exact maximum provisional. Length is a recorded maximum; mass is a rounded adult reference.
Bite evidence
Dwarf lanternshark: No standardized maximum is available. 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
One of the smallest known sharks also produces light. A small mouth and powerful suction suit its bottom-feeding life.
