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; Lemon shark by commonly to 3 m / 10 ft. Tiny sample sizes make the exact maximum provisional. The values are upper-end figures, not a typical adult profile.

Bite evidence

Dwarf lanternshark: No standardized maximum is available. Lemon shark: No standardized maximum is available for a fair cross-species comparison.

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. Decades of field research make this one of the best-studied coastal sharks.
