How many arms does an Octopus have?

Did you guess 8?

Well you are wrong. According to a new study they have six arms .... and two legs.

One can assume that the front six tentacles have the function of arms, and that the back two take over the function of legs," said Sea Life biologist Oliver Walenciak.

Unlike humans and some other animals, most octopuses did not appear to be left-handed or right-handed. Those that were suffered from eye problems on their less-favoured side.

"People have always assumed that octopuses coordinate their ... gripping behaviour through visual data. That seems to be true. When one eye is weak, another side of arms is favoured," said Walenciak.
