How Big Are Salmon Sharks? Typical & Maximum Sizes

Salmon sharks are powerful, fast-swimming predators inhabiting the cold waters of the North Pacific Ocean. They possess a stocky body, a pointed snout, and a crescent-shaped tail, making them highly efficient hunters. Their coloration typically ranges from dark blue-gray to black on their dorsal side, with a paler underside that often features dark blotches in adults. As apex predators, salmon sharks play a significant role in their marine ecosystems.

Typical Adult Dimensions

Adult salmon sharks commonly reach lengths between 6.5 and 8.6 feet (2 to 2.6 meters). Their typical weight can be up to 485 pounds (220 kilograms).

There can be some variations in size between sexes, with females generally tending to be slightly larger than males. For instance, females in the eastern North Pacific are often larger and heavier-bodied compared to those in the western North Pacific. These figures illustrate the robust build of a typical adult salmon shark.

Record-Breaking Sizes

While most adult salmon sharks fall within a common size range, some individuals grow to extraordinary dimensions. The largest reliably documented salmon sharks have reached a total length of about 10 feet (3.05 meters). These exceptionally large sharks can weigh over 992 pounds (450 kilograms).

There have been unconfirmed accounts of salmon sharks reaching even larger sizes, possibly up to 12.1 to 14.2 feet (3.7 to 4.3 meters). However, these larger unverified reports may sometimes result from confusion with the more massive white shark, which shares a similar appearance.

Putting Their Size in Perspective

A typical adult salmon shark, measuring between 6.5 and 8.6 feet, is roughly the length of a small pickup truck bed or a large couch. The largest documented individuals, at about 10 feet long, are still shorter than most standard passenger cars, which can range from 15 to 16 feet in length.

When compared to humans, a salmon shark can be more than one and a half times the height of an average person standing upright. While often mistaken for great white sharks due to similar body shapes, salmon sharks are considerably smaller. Great white sharks can grow to 16 feet or more, meaning a salmon shark is typically about half the length of an average great white.
