If GrrlScientist can do it with birds, then I can do it with fish. Just this once. There is, however, one difference (apart from the obvious one, that is). Whereas GrrlSicentist knows which bird it is before she sets the puzzle, I have absolutely no idea what sort of fish this is.
It's quite big - about 40cm long - and I found it washed up on Cromer East Beach as Canis croxorum and I took our lunchtime constitutional. I can't find it in my beachcomber's field guide, which covers the seashore and shallow seas of Europe, which suggests that I've skipped the relevant page, or that this is a species found in the open ocean. This pelagic habit is suggested by the laterally compressed shape, the depth of the body, the smooth, domed forehead and the rather rakish set of the median fins. That eye looks enormous, and that mean-looking piranha-like mouth was full of nasty sharp pointy teeth. The natural colour has probably faded from what was probably a silvery sparkle in life, and the ugly red blotch was probably caused by seagulls who got to it before I did.
So, people, you know what to do - Name That Fish!
