Aerial view of groups of sea lions in offshore waters near Cordova Alaska taken from an ultra-light plane
linkTwo groups of sea lions can be seen some distance away from the shore in deeper water. Sea lions are herring predators, feeding on herring while they spawn. Therefore, the presence of sea lions can be indicative of the presence of herring. However, herring schools are absent in this image.
