How do cephalopods reproduce?

Cephalopods are either male or female.  When it is time for mating, the female will often display a certain color.  The male will mate with her and will deposit a package of sperm into the female's pallial cavity by use of a specialized tentacle called a hectocotylus.  When ready, the cephalopod female lays her eggs and octopuses actually guard their eggs until they hatch, at which time the larvae emerge as fully formed miniatures of the adult.  The female octopus does not eat while guarding her eggs and by the time they hatch she generally dies as she is too weak to defend herself against predators.
