Megalodon is about 4.3× longer by these reference values.
Megalodon uses a 15.3 m upper reference, compared with 3.54 m for Zebra shark. Megalodon's weight reference is about 1371× 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.
THE NUMBERS
Side by side.
WHAT SETS THEM APART
More than a size contest.
Length and weight
Megalodon is represented by evidence-based upper estimate 14.1–15.3 m / 46–50 ft; Zebra shark by reported to 3.54 m / 11.6 ft. No complete skeleton exists; 15.3 m is an evidence-based maximum from museum specimens, not a tape measurement. Its very long tail adds substantially to total length.
Habitat and diet
Megalodon: Warm and temperate seas worldwide; large marine mammals, turtles and fishes. Zebra shark: Tropical Indo-Pacific reefs and sand flats; mollusks, crustaceans and fishes.
Bite evidence
Megalodon: Finite-element scaling produced a range, not a directly measured bite. Zebra shark: No standardized maximum is used.
Fossils change the certainty
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
