SHARK VS SHARK

Horn sharkvsOceanic whitetip

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

Oceanic whitetip is about 3.3× longer by these reference values.

Oceanic whitetip uses a 4 m upper reference, compared with 1.22 m for Horn shark. Oceanic whitetip's weight reference is about 17× 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

Horn shark is represented by reported to 1.22 m / 4 ft; Oceanic whitetip by reported to 4 m / 13 ft. Weight is a rounded adult reference. The comparison deliberately distinguishes the record from common size.

Bite evidence

Horn shark: Experiments also measured bites; the displayed range is the study's theoretical maximum from front to rear teeth. Oceanic whitetip: A traceable, species-wide maximum is not 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 rear teeth crush hard prey, and its bite mechanics have been tested directly and modeled. Most individuals are under 3 m even though larger records exist.
