Argonauta argo is a species of octopus. Members of family Argonautidae are known for their acute sexual dimorphism, females with webbed dorsal arms capable of secreting calcareous egg cases, and dwarf males with hectocotylized third arms used for fertilization. Argonauta nodosa, also known as the knobby or knobbed argonaut, is a species of pelagic octopus.The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell (hence the name paper nautilus). The argonauts are a group of octopuses unlike any other. The females secrete a thin, white, brittle shell called the paper nautilus. Nestled with their arms tucked inside this beautiful, translucent home, they drift through the open ocean while other octopus species crawl along the sea floor. Argonauts, several species in the genus Argonauta, are a group of octopod cephalopods, the group that contains all the eight armed, soft bodied cephalopods.

Which brings me to the argonaut octopus and a paper published today in the Proceedings of the Royal Society by Julian Finn and Mark Norman. The argonaut is sometimes called the "paper nautilus" because of its superficial resemblance to the chambered nautilus, but the two are only distantly related.
