SHARK VS SHARK

MegalodonvsTiger shark

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

ExtinctOtodus megalodon×LivingGaleocerdo cuvier
QUICK VERDICT

Megalodon is about 2.8× longer by these reference values.

Megalodon uses a 15.3 m upper reference, compared with 5.5 m for Tiger shark. Megalodon's weight reference is about 53× 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

Megalodon is represented by evidence-based upper estimate 14.1–15.3 m / 46–50 ft; Tiger shark by largest specimens exceed 5.5 m / 18 ft. No complete skeleton exists; 15.3 m is an evidence-based maximum from museum specimens, not a tape measurement. Both values describe exceptional animals, not an average adult.

Bite evidence

Megalodon: Finite-element scaling produced a range, not a directly measured bite. Tiger shark: Popular figures are often repeated without a traceable species-level method.

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

Nearly every whole-body number is reconstructed from teeth and comparisons with living sharks. Its broad diet is real; an exact maximum bite number is not well established.
