With two better than eight

Two small octopus from the tropics, when they want to flee from the aggressors, move to two legs and the rest is used to change their appearance.
Octopus marginatus, for example, takes the form of coconut with the six arms grouped around the body, and the other two uses them to go out on foot. Lives in Indonesia and on its seabed there are numerous coconuts, so it is very useful for him to adopt a form of coconut that becomes invisible to the aggressors.
The other octopus, Octopus aculeatus, is a little smaller and shaped like algae. Thanks to this he hides from the aggressors and, if it were not enough, is able to walk on the two legs like the other.
According to researchers, there is still a lot to know about octopus, and these two may not be the only ones able to walk to two legs. The research has been published in the journal Science.
