A salmon is a big, silver-skinned fish that lives in both the Atlantic and Pacific oceans. Many commercial fishermen catch salmon.
Salmon are born in fresh water, migrate to the ocean, and then return to the place they were born to spawn, or reproduce. Because they move from one place to another, salmon are famous for leaping over dams and against river tides — in fact, one theory about the word salmon says its Latin root is salire, or "to leap." There is also a color known as salmon, the pink-orange hue of a salmon's flesh.
