[CT] glow-in-the-dark fish

[Dan Moran]

Bugs can see uv; that's why bug zappers are attrative to them. Birds can
too -- I don't know if it's all bugs & all birds, but certainly some of
each. It seems certain that birds & bugs don't look to each other the
way they look to us. I'd bet there are fish that can see UV too, though
I don't know that for sure.

Far as I know, there hasn't been a lot of research done on this -- not
that I would necessarily know. But I haven't run across any.
