Why do fish hide their eyes? The truth behind the colour.

Lion-Fish.jpgYou may notice that some of the most beautiful fish have elaborate patterns, and sometimes these patterns are even imprinted onto their eyes. Why is that?

Well, fish only do a few things in life. They eat, mate and avoid predators.

fishPredatory fish are always looking for a tasty snack. In order to judge the size of potential dinner, predators will look at the eyes of other fish to determine their size and thus how easy they will be to capture. By having stripes or camouflaged eyes, the predator will become confused and so the fish will less likely be eaten.

Furthermore the stripes will confuse the predator, giving the fish time to escape, which means the fish can go on to live another exciting day.
