Dolly Varden (Salvelinus malma) 

 Dolly Varden are often confused with Arctic char. Dolly Varden generally have a green gray body with many small spots and a slightly-forked tail. Arctic char, in contrast, generally have a bronzish-yellow body with fewer and larger  cream-to-orange colored spots, and a noticeably-forked tail. Spawning male Dolly Varden usually develop a distinct kyped jaw, which is absent or reduced in spawning male Arctic char. In Alaska, Dolly Varden spawn and usually live in streams and rivers and may migrate to and from the ocean, but Arctic char in Alaska generally complete their entire life cycle in lakes.
