The octopus is a mollusk and belongs to a sub-species called cephalopod. The plural form of octopus is octopuses or octopi or octopede. They are invertebrates, which means that they have no bones whatsoever in their bodies, neither internally or externally. This aspect allows them to go through very tight places and squeeze through rocks or live in spaces in which other animals cannot reach them. The only hard part in octopuses is their beaks. They use their beaks to bite and also to release poisonous saliva that is used usually to subdue their prey. They also have very good eyesight with which they can spot their prey and know the best place to grab it.
