My quest for the real trout

[Ktrout]

Sounds like you had fun reading all of that.

Common names often don't have a scientific basis and are also not universal (the common name changes depending on geographic location). They are however useful for conversation, unlike scientific naming. When you try to group common names, it usually doesn't work out based on the actual names.

So people can debate what's a "true trout", but scientifically, they may not have a leg to stand on. I'd like to see what makes a trout a trout, scientifically?
