The argonauts (genus Argonauta, the only extant genus in the Argonautidae family) are a group of pelagic octopuses. They are also called paper nautiluses, referring to the paper-thin eggcase that females secrete.

Female argonauts produce a laterally-compressed calcareous eggcase in which they reside.
