SHARK VS SHARK

Bull sharkvsFrilled shark

Length, weight and bite evidence—plus context from a human, city bus and blue whale. Every number below carries its uncertainty with it.

QUICK VERDICT

Bull shark is about 2.0× longer by these reference values.

Bull shark uses a 4 m upper reference, compared with 2 m for Frilled shark. Bull shark's weight reference is about 21× heavier.

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.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Bull shark is represented by reported to 4 m / 13 ft; Frilled shark by about 2 m / 6.6 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Deepwater records remain limited.

Bite evidence

Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. 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 freshwater range is exceptional among large coastal sharks. Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils.
