New research has found that octopus have a preferred tentacle, much as humans have a preference for using either their left or right hands.
It was previously believed that octpus would use whichever of their eight tentacles was closest when feeding.
According to The Telegraph, Drs Ruth Bryne and Michael Kuba from the University of Vienna have found that octopus have a preference over which of their tentacles to use.
They kept octopus in aquaria and gave them items to investigate and found that they tended to mainly use one of their front tentacles.
