SHARK VS SHARK

Oceanic whitetipvsOtodus obliquus

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

Otodus obliquus is about 2.3× longer by these reference values.

Otodus obliquus uses a 9.1 m upper reference, compared with 4 m for Oceanic whitetip. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.

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

Oceanic whitetip is represented by reported to 4 m / 13 ft; Otodus obliquus by estimated to about 9.1 m / 30 ft. The comparison deliberately distinguishes the record from common size. Soft-body dimensions are inferred from teeth and living analogues.

Bite evidence

Oceanic whitetip: A traceable, species-wide maximum is not available. Otodus obliquus: No species-specific model is used.

Living versus extinct

At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.

Ecology changes the matchup

Most individuals are under 3 m even though larger records exist. It belonged to the megatooth lineage that later produced megalodon.
