Um...that thing has very few spots and most of what it has are localed near the tail. This leads me to beleive this is a cutthroat suspecies. Im to lazy to look in benke's book right now to see which one it is, but i do belive the rio grande cutthroat has a few different subspecies. I could see why u would think it is a bow, and it very well could be...the silvery coloration doesnt seems that typical of most cutties, maybe the bear lake strain when its living in lakes. Who knows, anyone else have opinions on what this thing is? Either way, pretty fish!
I just today scoped out Behnke's book, and I see what you mean. I only wish I had a better pic of the fish; the glare seems like it could be hiding more spots. Just the same, it could be a Rio Grande Cutthroat. Only because I find that so much more cool than the fish being a rainbow, I hesitate to jump too quickly to asserting that the fish is a RGC. Still, thanks for pointing this all out.
