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
Blue shark is represented by about 3.8 m / 12.5 ft; Frilled shark by about 2 m / 6.6 ft. Upper records are uncommon; most adults are lighter. Deepwater records remain limited.
Bite evidence
Blue shark: No comparable maximum is used. 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
Its long fins and slender build matter more than raw bulk. Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils.
