Bonneville Cutthroat Trout
Bonneville Cutthroat Trout generally have large, evenly distributed spots, but there can be a high degree of intra-basin variation. Bonneville Cutthroat Trout tend to develop large pronounced spots that are more evenly distributed on the sides of the body rather than concentrated posterior as in the Yellowstone subspecies. Coloration in BCT trout is generally dull compared to other cutthroat trout subspecies. But coloration can vary depending on environmental conditions and local genetic composition. It has the notable vibrant red slash under it jaw that is characteristic of all cutthroat species.
