Therefore, the real distinguishing difference between a Cutthroat Trout and a Rainbow Trout is that Cutthroat Trout have a set of basibranchial teeth at the base of their tongue and a maxillary that extends beyond the posterior edge of the eye. gairdneri ) populations also display reddish or pink throat markings. irideus ) and Columbia River Redband Trout (O. However, it should be noted that these markings are not unique to the species since some coastal rainbow trout (O.

However, they are also commonly found inhabiting eastern streams throughout the Appalachian Mountains as well as some northern lakes where it is believed that they were transported and stocked by unknown individuals.
