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.
THE NUMBERS
Side by side.
WHAT THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Frilled shark is represented by about 2 m / 6.6 ft; Nurse shark by recorded to 3.08 m / 10.1 ft. Deepwater records remain limited. Length is a recorded maximum; mass is a rounded adult reference.
Bite evidence
Frilled shark: No standardized maximum is available. Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings.
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
Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils. A small mouth and powerful suction suit its bottom-feeding life.
