Fish Can Count Numbers

Fish are not just cold-blooded aquatic vertebrates but little smart too. According to new research fish can count. Scientists have found that North American mosquito fish have the ability to count up to four. Fish have a limited ability to count how many other fish are nearby. This means that they have similar counting abilities to those observed in apes, monkeys and dolphins and humans with very limited mathematical ability.
