QUICK VERDICT

Bull shark is about 19× longer by these reference values.

Bull shark uses a 4 m upper reference, compared with 0.21 m for Dwarf lanternshark. Bull shark's weight reference is about 1583× heavier.

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

Bull shark is represented by reported to 4 m / 13 ft; Dwarf lanternshark by about 0.21 m / 8.3 in. The 4 m figure is a reported maximum; typical mature animals are smaller. Tiny sample sizes make the exact maximum provisional.

Bite evidence

Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. Dwarf lanternshark: No standardized maximum is available.

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 freshwater range is exceptional among large coastal sharks. One of the smallest known sharks also produces light.
