On Facebook, this came from Michael Palmer, who got it from Seth Andrew. (As with many such things, the creators of the image and the text are not identified.)
A penguin image altered to show a classic carnivore’s mouth, with its very prominent canine teeth. (In the real world, carnivores have such dentition, but then so do a number of herbivores. Evolution is complicated.)
Side benefit: the -ocalypse word penguinocalypse. The usual libfix is –pocalypse; this version is shortened to improve on the somewhat awkward penguinpocalypse (with its /n – p/ sequence).
