Nature: The Fisher...Man?

In a peculiar twist of roles, a certain pond dweller has inexplicably learned to...fish?  Relaxing on a comfortable chair, shaded by his straw hat, holding a fishing pole; nothing out of the ordinary right? But, wait a second, this fisherman is under water, and using a hotdog as bait, that is a little odd. Strangest of all is this fisherman doesn’t seem to be a man, but a fish! What do you call a fish fisherman? A fisher fish? A fishing fish? This discussion could go on for a while. Just remember, if you see a hotdog sticking up out of a pond, don’t try eating it!
