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; Shortfin mako by reported to about 4.45 m / 14.6 ft. Tiny sample sizes make the exact maximum provisional. Record length and mass do not necessarily describe the same individual.

Bite evidence

Dwarf lanternshark: No standardized maximum is available. Shortfin mako: No directly comparable maximum bite-force estimate is used.

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. Speed is its signature; the biggest animals are unusual and hard to verify.
