SHARK VS SHARK

Basking sharkvsBull 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

Basking shark is about 3.0× longer by these reference values.

Basking shark uses a 12 m upper reference, compared with 4 m for Bull shark. Basking shark's weight reference is about 19× 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

Basking shark is represented by reported to 12 m / 40 ft; Bull shark by reported to 4 m / 13 ft. The upper length is exceptional; the mass is a rounded comparison estimate. The 4 m figure is a reported maximum; typical mature animals are smaller.

Bite evidence

Basking shark: A comparable maximum-bite study is not available for this filter feeder. 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.

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 enormous mouth strains plankton; it is not built for a giant predatory bite. Its freshwater range is exceptional among large coastal sharks.
