John Dory
The John Dory has a high laterally compressed body – its body is so thin it can hardly be seen from the front. The large eyes at the front of the head provide it with the binocular vision and depth perception it needs to catch prey. It has a large dark spot on both sides which it uses to flash an "evil eye" if danger approaches. This eye spot also confuses prey, which can then be sucked into its mouth.
