Recently I was gifted a particularly beautiful shell by a friend who knew that I liked to collect such things. The shell was paper thin, translucent, and covered in rows upon rows of little bumps. I was in love.
This curious specimen sparked a research rampage on my part until I tracked down the original owner of the shell and it’s story.
|The newest shell in my collection - an Argonauta nodosa egg case|
It turns out that my shell is not strictly a shell; it is in fact the egg case of a female Argonauta nodosa – commonly referred to as a Paper Nautilus. Argonauts are a group of pelagic octopuses and the lady Argonauts make these delicate egg cases to use as a brood chamber and also to help control their buoyancy in the water. Cool huh!

As you can see in the images this octopus sits very differently to most other octopuses. Female argonauts slip themselves into the egg case so that their mouth is exposed at the front and their eight arms are tucked back into the case. The females have two specialised webbed tentacles that secrete the shell and can be wrapped around the egg case to hold it in place. They move around with the help of an enlarged funnel that they use to jet around the place. The chromatophores in the octopus's skin allow it to shift from a almost translucent white colour to a vivid purple, red or orange in a split second.

I have always been a lover of cephalopods and have previously created artworks inspired by the shells of the Nautilus and Ammonites (a prehistoric cephalopod). But I think these little guys are now my new favorite. They are just so weirdly wonderful! See the bottom of this post for links to a great video and some further readings.
So once I knew a bit about these creatures I just had to create an embroidered artwork based on these beautiful egg cases. Although my egg case came from a species that is local to Australia; Argonauta nodosa (commonly known as the knobbed Argonaut) my design was based on the more widely distributed Argonauta argo (also knows as the greater Argonaut).
I was torn between creating a bright colourful interpretation of the shell or a subtle white piece that more closely referenced that natural colouring of the egg case.
So in the end … I made both.

After mapping the ribbed pattern on an Argonauta argo egg case I created a brightly coloured piece using my favourite colour scheme of reds and oranges. I moulded the piece when it was drying to give it a subtle curved shape and pinned its edges directly down onto the mounting board so that it retained this three dimensionality within the narrow box frame.

I loved the bright red/orange version of the shell but I still wanted to attempt a white version. White has always been a difficult colour for me to work with because I have to restrict my drawn guidelines so I don’t stain the white yarn. But after a bit of experimentation (and a few close calls) I was able to replicate the design in pure white.

This white piece was very difficult to capture (forgive my crappy, over edited image above – white on white is tricky to shoot) Unfortunately the photo’s don’t capture the depth and subtle texture of this piece - but hopefully you can still get a bit of a feel for the piece.
Want to see these artwork in the flesh? They will be on show at Arcadian Artists in November 2016.
