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

Dwarf lanternshark is represented by about 0.21 m / 8.3 in; Tiger shark by largest specimens exceed 5.5 m / 18 ft. Tiny sample sizes make the exact maximum provisional. Both values describe exceptional animals, not an average adult.

Bite evidence

Dwarf lanternshark: No standardized maximum is available. Tiger shark: Popular figures are often repeated without a traceable species-level method.

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. Its broad diet is real; an exact maximum bite number is not well established.
