How long does a octopus live?

*Octopuses* have a relatively short life span, and some species live for as little as six months. Larger species, such as the North Pacific Giant Octopus, may live for up to five years under suitable circumstances. However, reproduction is a cause of death: males can only live for a few months after mating, and females die shortly after their eggs hatch, for they neglect to eat during the (roughly) one month period spent taking care of their unhatched eggs. [Octopuses are highly intelligent,*** probably more intelligent than any other order of invertebrates. The exact extent of their intelligence and learning capability is much debated among biologists
