- Argonauta nodosus [previously known as 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 shell is usually approximately 150 mm in length, although it can exceed 250 mm in exceptional specimens; the world record size is 292.0 mm. A. nodosus produces a very characteristic shell, which is covered in many small nodules on the ridges across the shell, hence the specific epithet nodosus and common name. These nodules are less obvious or even absent in juvenile females, especially those under 5 cm in length. All other argonaut species have smooth ridges across the shell walls. A. nodosus has a relatively wide distribution covering the Indo-Pacific region as well as the eastern coast of South America. The species is most common in southern Australia, New Zealand, and South Africa. It is only known from the Southern Hemisphere. A. nodosus is thought to feed primarily on pelagic molluscs. Captive females have been observed readily taking dead prawns and fish. The species is preyed on by numerous predators. It has been reported in the stomach contents of Alepisaurus ferox from the south-western Pacific. A. nodosus has also been found in the stomach contents of Australian fur seals, Arctocephalus pusillus doriferus, in the Bass Strait and southern Tasmania. Females grow to 100 mm ML and 300 mm total length, while males do not exceed 40 mm in length. The specialised webbed arm pair of this species is covered in numerous chromatophores. Mark Norman notes that "the colour of these webs can quickly change from maroon red to reflective silver". It has been reported that the egg clusters of A. nodosus from southern Australia can be clearly divided into three portions, each with eggs at a similar developmental stage. Similar development has been observed in the egg masses of Argonauta bottgeri. A. nodosus is occasionally involved in mass strandings along the South African and southern Australian coastlines. The strandings are seasonal and generally occur between April and August, towards the end of the animals' spawning season. The type specimen of A. nodosus was collected off the Cape of Good Hope. The is unknown.

- De papiernautilus (Argonauta nodosa) is een soort in de taxonomische indeling van de inktvissen, een klasse dieren die tot de stam der weekdieren (Mollusca) behoort. De inktvis komt enkel in zout water voor en is in staat om van kleur te veranderen. Hij beweegt zich voort door water in zijn mantel te pompen en het er via de sifon weer krachtig uit te persen. De inktvis is een carnivoor en zijn voedsel bestaat voornamelijk uit vis, krabben, kreeften en weekdieren die ze met de zuignappen op hun grijparmen vangen. De inktvis komt uit het geslacht Argonauta en behoort tot de familie Argonautidae. (nl)
