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; Frilled shark by about 2 m / 6.6 ft. Tiny sample sizes make the exact maximum provisional. Deepwater records remain limited.

Bite evidence

Dwarf lanternshark: No standardized maximum is available. Frilled shark: 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

One of the smallest known sharks also produces light. Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils.
