Argonaut or Paper Nautilus

Vintage illustration of an Argonaut, also called a Paper Nautilus. The argonauts (genus Argonauta, the only extant genus in the family Argonautidae) are a group of pelagic octopuses. They are also called paper nautiluses, referring to the paper-thin egg-case that females secrete. This structure lacks the gas-filled chambers present in chambered nautilus shells and is not a true cephalopod shell, but rather an evolutionary innovation unique to the genus Argonauta. It is used as a brood chamber and for trapped surface air to maintain buoyancy. This image has been colour enhanced.
