Limpet

Southern, Jen (2022) Limpet. [Performance]

Abstract

Limpet was a contribution to the day long workshop ' Rock Up!' led by the Rocky Climates Network for Art Houses Festival 2022. Limpet was a performative conversation, suggesting that limpets could be thought of as translators between humans and rocks. Limpets live as close to rock as they can get, and over time they grind into the rock making a 'homescar' and altering their shell in order to make a seal so that no water escapes at low tide. This means that they are almost perfectly adapted to a constantly changing environment that can cycle from hot and dry to cold and wet twice a day with the tides. This homescar can sometimes be seen on the rock as a round mark or indent, and over time when the limpet has died, they seem to erode further to create small cups in the rock that are reminiscent of rock graves that once held the fleshiness of human bodies at Heysham and Whitby. Shells become rock. On the beach at St Mary's we found fossils of shells within stone made from sedimented sand that includes ground up shells. Limpet shells are made from calcium carbonate in the water, and sometimes become the same colour as the rock. Their mouth parts - the radular - is the hardest bio-material that scientists have found, harder than the rock that it wears into. When the tide is in the limpets roam around the rock using the radular to scrape algae off the surface, gradually eroding the surface, as small rocky sculptors. They leave a slime trail, and follow it back to their homescar as the tide falls, in order to clamp down again before they are exposed to the air. I invited participants to find a limpet shell, and scoop up some clay, and then stick it to the rock and move it in emulation of the limpets roaming movements, and to think about the limpet becoming rock and rock becoming limpet as their surfaces mould to one another.
