i do not belive so but i know it can grow a tail back
Yes, if it loses one it will regrow one.
Yes. It can regrow another arm. But the severed arm will not regrow into another octopus.
Yes
By what i researched so far it does!
Yes, an octopus can regrow an arm that gets torn off.
Yes although,It will take a couple of months but the limb will be fully functional again once its completely done.
The arm of an octopus is called a tentacle.
regeneration
The starfish is an amazingly diverse aquatic animal. The starfish is able to regrow an arm, and able to regrow a whole new body from a detached arm.
The octopus nervous system is different from a mammal's. The brain of the octopus does not have complete control over the body. The tentacles of the octopus contain ganglia which can operate separately from the octopus body. The octopus does not directly control it, but instead sends commands to the arms and lets them do the work. Octopus have little to no proprioception. When an octopus loses an arm, it can no longer control it (obviously). Because the ganglia are still intact, it is still capable of operating independently of the octopus. The independent arms can react to stimuli as it did when it was still connected to the octopus, though it has not been proven that the arms themselves are actually self-aware and not just automatic responses. If lost, an octopus can regenerate an arm. This occurs during mating, when an octopus's Hectocotylus (mating arm) often breaks off and is left in the female.
yes
It grows a new one. If a salamander loses a limb it can still grow a new one. Mammals are a little jealous of this ability of the lower animals. If you remember your spider-man comics the super-villian 'the lizard' started out as a scientist trying to regrow his severed arm.
