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

Pacific sleeper shark is represented by reported near 7 m / 23 ft; Tiger shark by largest specimens exceed 5.5 m / 18 ft. Large values often depend on indirect or incomplete records. Both values describe exceptional animals, not an average adult.

Bite evidence

Pacific sleeper shark: No standardized maximum is available. Tiger shark: Popular figures are often repeated without a traceable species-level method.

Living versus extinct

Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.

Ecology changes the matchup

Rare encounters make its maximum size less certain than familiar coastal species. Its broad diet is real; an exact maximum bite number is not well established.
