As I'm studying for an ichthyology course I'm reminded of all the neat fish I've been able to work with. Most have been preserved specimens but it's still been interesting. The list has included things like pike, gars, bowfins, sturgeons, seahorses, and many other species.
However, I think that the neatest fish that I've been able to see in person is a coelacanth

Of course it was preserved but I feel very fortunate to have been able to see one up close and personal. I don't think that many people get that opportunity
What's the neatest fish that you've seen in person (alive or dead)? Given the opportunity, what is the fish that you'd want to see the most?
It is absurd to talk of one animal being higher than another. We consider those, when the cerebral structure/intellectual faculties most developed, as highest. A bee doubtless would when the instincts were.
