Sea-run Atlantic salmon (Salmo salar) are bright and silvery, with a bluish-green dorsal area shading to white below. In freshwater, they turn dark gray to reddish brown. Adult Atlantic salmon average 30 inches in length and typically weigh 7 to 12 pounds. Their latin name means "the leaper," as they are able to leap up to 12 feet over obstacles, if conditions are right. Juvenile salmon, residents in freshwater streams in the basin, look so similar to trout that the species are often confused. Coloration and size can be identical. Juvenile salmon have a shorter mouth and a more forked tail than trout, but often these features can be distinguished only upon careful inspection.
