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; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Large values often depend on indirect or incomplete records. Upper records vary by region and source.

Bite evidence

Pacific sleeper shark: No standardized maximum is available. Sand tiger shark: A reliable comparable maximum was not found.

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 protruding teeth look dramatic, but appearance alone does not reveal bite force.
