fish enjoy playing

相信大多數人都享受玩樂的喜悅,但你有想過原來魚兒也愛玩?研究員發現缸裡的灰體藍首魚會在無實際目的下敲擊缸裡的温度計,而這行為與食物或其他同伴無關,所以猜測牠們是為了玩樂。另一研究也發現章魚會重複地把球拉到水裡,並看它彈回水面。

i bet most of the people enjoy playing and having fun, but do you know that fish like play as well? researchers found that the white spotted cichlid in the tank would repeatedly strike the bottom-weighted thermometer just for fun, and with out any effect on food or companions. another research has observed an octopus playing with a ball by pulling them underwater and watching it pop up again
