Caption

Coho salmon are seen swimming together. A new study has found that Pacific salmon, including coho, school together in the open ocean to lower their risk of being eaten by predators. (Note: This photo was taken at the Seattle Aquarium and serves to illustrate this grouping concept in the wild.)
