  • Look for the distinctive red or orange slash marks under the jaw. This cutthroat marking is the easiest field identifier.
  • The body is typically olive-green to golden-yellow with small, irregularly shaped black spots concentrated more toward the tail end.
  • Unlike rainbow trout, the Colorado River cutthroat lacks a strong pink or red lateral stripe running along its side.
  • The spots on this fish tend to be rounder and more evenly sized compared to the larger, more irregular spots seen on brown trout.
