Graylings sound like wild beings out of a fantasy series, but in fact they’re a type of fish found all over the world in different species, some threatened with population decline, and some stable. The Arctic grayling, found in Russia and Canada but also some areas in Alaska, Montana and Wyoming, has suffered extirpation from certain spots in the latter two states during the last hundred years or so, due to anthropogenic effects. Ted Williams reports for The Nature Conservancy:

The Arctic grayling’s spotted, orange-trimmed dorsal fin looks as if it had been photoshopped. It’s half as long as the body and just as wide; and it glows with impossible shades of violet, green and turquoise. This gaudy trout cousin was deposited by the retreating glacier in the coldest, clearest waters of the contiguous states.

So common…
