Argonaut octopus eggcase shell. Egg case from a female greater argonaut (Argonauta argo) found in the Indo-Pacific. Argonauts are a group of pelagic octopuses. They are also called paper nautiluses, referring to the paper-thin eggcase (seen here) that females secrete. This structure is not a true cephalopod shell, but an evolutionary innovation unique to the Argonaut genus. It is used as a brood chamber and for trapped surface air to maintain buoyancy. Argonauts are found in tropical and subtropical waters worldwide. This specimen measures 185mm long.
