Fish have natural rhythm to avoid predators
A study published in Nature demonstrates that fish have a natural rhythm that could help them avoid being eaten by predators
A team from the University of California led by Dr Mu-Ming Poo made the discovery during experiments with zebrafish, a type of minnow. They discovered that the larvae of the fish, which were trained to flip their tails every time a light flashed at six-second intervals, "remembered" the rhythm even after the flash was turned off.
The reason why the fish kept time was a mystery but it could be to help it keep track of time and defend itself.
