The news has been a little depressing lately with some sad conservation issues, here is an interesting science article.
The researchers believe that fish have an innate "metronome" which helps them remain on a beat and could be used to let them know where they are and also swim in a co-ordinated fashion.
The team at University of California led by Dr Mu-Ming Poo made the discovery during experiments with zebrafish, a type of minnow, in Berkeley, California.
They discovered that the larvae of the fish, who 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.
