An octopus is reaching for a freshly amputated arm of another conspecific octopus and pulls it. Since the amputated arm is still alive, it holds the glass firmly, and the octopus has to use two arms in order to pull it. The amputated arm is pulled by the octopus and brought into the mouth and is held in it as a typical food item.
