Time for an update on the limpet situation. I picked up my latest batch this week and feel like I'm getting somewhere: their form is much blousier, and I'm finally getting the porcelain thin enough for light to shine through. Incredibly exciting, because for me, its translucency is the most mesmerising thing about porcelain. I'm intending to try firing some of these with in a matt, translucent glaze, but in the meantime, I settled the colony in on my windowsill, and peered over the laptop at them as I worked to see how they would behave. As soon as the sun hit the windowsill, they began to glow with a lovely submerged golden light, making me think this species is one of those furnished with photophores: light-emitting cells. Speculate that these may attract prey to within the reach of the hunting limpet.
My feeling about these limpets has been that they should seem subtly animated in some way, but I wasn't quite sure how this would happen. I've had ideas about an installation where they move up and down the walls of a gallery space 'with the tide'; and I noticed that the ones with a single feeding pore gave the impression of having a vestigial face. When I tilted a couple towards each other, they seemed to be communicating or negotiating.
Instead of a single large feeding pore, some have a ring of small holes around the shell (females?) Through these emerge fans of retractable 'hairs' with which they sweep the current in search of their very small beer.
