The Alaska blackfish, Dallia pectoralis, is a fish that grows to 7 in (180 mm) in length. It is elongated and cylindrical, with a dark olive-brown coloration. Four to six dark blotches run vertically along the sides, and the belly is white. The fins have reddish-brown speckles. Once thought to be an herbivore, its primary diet is midges and mosquito insect larvae.
