I wasn't, until I discovered by reading your post one minute ago that it was a thing.

Yes they are a thing, somewhat controversial as well, they suddenly appeared in some guys aquarium several years ago, a mutation. They have become established in the wild in a few places, they out reproduce naturally reproducing crayfish. I had two to start with couple months ago, I bought them as a food source for my mudpuppy, now i have dozens and dozens of them. 

Very interesting
