Female octopuses stretch further
Scientists in Italy developed this method of measuring octopuses' arm extensions
Female octopuses go to extra lengths when stretching their arms to reach food, a study has found.
Scientists in Italy measured octopuses' arm extensions as they reached up a tube towards tasty bait.
They found for the first time that octopuses' arm elongation ability differed depending on their sex and size.
The findings are published in the Journal of Experimental Marine Biology and Ecology (http://www.sciencedirect.com/science/article/pii/S0022098113000774).
