Male and female adults usually die shortly after spawning and brooding, respectively. In an indirect way, it also means that the common octopus has been of invaluable assistance to marine biologists in determining the precise composition of ocean fauna for a specific area. Like the rest of the over 300 octopus species, the octopus Vulgaris is a mollusk. Nauen.
