Species of pacific salmon commonly 18-30 inches in length with a chunky body, brick red sides and a silver top. Coho spawn in early winter (Nov. - Jan.) and die shortly after laying their eggs. They are similar in appearance to the Steelhead but lack the distinctive spotting on their backs. Coho also have a continuous red side and underbelly where as the Steelhead have a band of red that streaks down their side.
