Comments: Cutthroat are similar to rainbow trout and will readily interbreed, producing fertile hybrids. Cutthroat trout vary widely in size, coloration, and habitats. Though their coloration can range from golden to gray to green on their backs, depending on subspecies and habitat, all populations feature red, pink, or orange marks on the bottom of their jaws, which are the easiest diagnostic of the species for the casual observer. As adults, different populations and subspecies of cutthroat can range from six to almost forty inches in length, which means size is not an effective indicator of the species.

There are about 14 separate subspecies of cutthroat trout.
