Figures a-b: 175 mm, Schouten Island, TAS (E), coll. S. Grove. Figure c: 45 mm, South Bruny Island, TAS (S), coll. S. Grove.

Typical shell-length 350 mm. The living paper-nautilus is a pelagic octopus; the ‘shell’ is the female’s temporary brood-chamber.  Lives in offshore waters in midwater.  Native. Occurs in southeastern and southwestern Australia (QLD, NSW, TAS, VIC, SA and WA); also widespread elsewhere in the warm temperate zone of the southern hemisphere.  In Tasmanian waters, this species is most regularly stranded around Flinders Island and along parts of the E coast; few shells survive beaching intact.
