Lo and behold! Fish CAN count! A new study recently commented on by the National Geographic shows that fish can in fact count as high as four. They gave the fish multiple exit options from a tank, with each exit marked with one to four shapes. The trick is, only the exit with four shapes opened. The shapes varied in size, shape and brightness, so the only way they could recognise the exit was to "count" the number of symbols. The results were not overwhelming, but the fish did choose the four symbol exit more often than by chance alone. Booya! Next time I go fishing, I'm going to use four lures instead of one.
