SHARK VS SHARK

HybodusvsWhitetip reef 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

Hybodus is about 1.17× longer by these reference values.

Hybodus uses a 2.5 m upper reference, compared with 2.13 m for Whitetip reef 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

Hybodus is represented by about 2.5 m / 8.2 ft; Whitetip reef shark by reported to 2.13 m / 7 ft. The genus spans a long interval and multiple species; this is a comparison reference. The species is usually smaller than its reported maximum.

Bite evidence

Hybodus: Tooth form suggests diet, not an exact force. Whitetip reef shark: No standardized maximum 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 was a shark-line relative, not a member of a living shark order. Its slim body lets it hunt inside reef crevices.
