Size is not the whole animal.

Length and weight

Bite evidence

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 protruding teeth look dramatic, but appearance alone does not reveal bite force.
