Some of the greatest survivors in nature are those that fool predators in order to derail their attack. This allows them to realise the threat and make their escape or fight back. Take, for instance, the juvenile Damselfish. When threatened by predators, this marine marvel shrinks its eyes and grows a large spot on its tail to look like an eye. Having such a decoy deceives anything wishing to dine on the Damselfish into attacking the tail rather than the head. The fish can then swim off to safety while at the same time circumventing its demise. Similar forms of cunningness can also be seen with butterfly fish, octopus, chameleons, and tree frogs, which are all adept at using various forms of camouflage as a defense against predators.
