Do fish have fisheyes?

Obviously somebody named the fisheye lens after a fish, but I wonder if fish actually have fisheye lenses, or do we just think they do because their eyes bulge kinda like the lenses?

I suppose it’s remotely possible somebody looked at a fish and said “hey – I think I’ll build a lens that works like that fish’s eye”. But I doubt it. Pretty sure the lens came before the name.
Why don’t we call telephoto lenses “eagleyes” or something? Dunno.

    Speaking of fisheyes, we once had a horse (not owned but in training) who we named Pike-Eye because he had an eye like a fish. He was a really ugly horse and being named Pike-Eye was the ulitimate insult, an unfortunatley it fit him to a T.
