Cartoon Fish

I was inspired to post this 6 year old photo by seeing another photo from a flickr friend, in which the back of a dragonfly's head looks similarly cartoonish.
This is the underside of a flounder, or angelfish, or some other type of flat fish. It looked quite boring right side up.
I would imagine there's probably a Group. : )
Taken at the Biodome (I think) in Montreal.
