hermit crabs

After it dies something else comes along and finds its empty shell — millions of years ago it was ammonites that died and left their whorled shells vacant and available for re-use; but ammonites disappeared 66 million years ago. Snail shells rose in popularity sometime after that — the whorled interior space that one never sees can be used as a safe place to hide or withdraw into. First the aperture of the shell must be examined and the hard surface inside palpated. Then she auscultates it by tapping on it. The female places her claw in her mouth to signal to the male of her species that she is ready to mate — but the shell is not hers , and whichever shell she chooses to use will eventually need to be replaced — crabs go through moults, developmental stages wherein they slough their entire body and leave it behind. Checks the feel of the shell inside and out , does she like the smell inside — the smell of dead crab is associated with potential empty shells and can be alluring on its own; she weighs the shell again and measures herself by it — can she retract herself inside.

The form is not bounded at the interface, it extends beyond the tissue into a mineral body that is not of her own making. Someone else's shell. Useless, until now. She holds onto the spiral by clasping the interior axis of its form, rooting her own body to its columella. The shell is taken up, but not owned; held, but never kept. A borrowed exterior, yes—but not simply assimilated, not absorbed into identity without remainder. It remains other even as it is carried, even as it functions as protection, even as it becomes necessary.

Form extends outward or inward through contact, through palpation and touching, and tapping. Through this process she defines a space that she can occupy. For a time she will use it as a home and withdraw into it when danger is near. But she will eventually vacate it and find a different shell. The hermit crab's life is lived cycling between shells just as a shell will cycle between crabs.

The organism, then, is not a stable body but a moving relation—a series of attachments and detachments, of graspings and releases, of interiors that were once exteriors and exteriors that may again be taken in. What appears as a continuous being is in fact composed through discontinuous acts—through vacancy, through availability, through the persistent possibility that what holds now will not hold for long.

Thus the form of existence here is not given but negotiated, not possessed but passed through—held only in the interval between what is occupied and what has just been left behind, between what fits and what no longer does, between one shell and the next.
