SHARK VS SHARK

Epaulette sharkvsOtodus obliquus

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

LivingHemiscyllium ocellatum×ExtinctOtodus obliquus
QUICK VERDICT

Otodus obliquus is about 8.5× longer by these reference values.

Otodus obliquus uses a 9.1 m upper reference, compared with 1.07 m for Epaulette shark. 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

Epaulette shark is represented by reported to 1.07 m / 3.5 ft; Otodus obliquus by estimated to about 9.1 m / 30 ft. Mass varies strongly with size and is shown only as a reference. Soft-body dimensions are inferred from teeth and living analogues.

Bite evidence

Epaulette shark: No standardized maximum is used. 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

It can use its fins to walk across reef flats and tolerate low oxygen. It belonged to the megatooth lineage that later produced megalodon.
