Crabs Are A Process
The word “crab” brings to mind a snapshot (or perhaps a scuttling mental video) of the surface appearance of an adult crab. Like most nouns, “crab” is a metonym for a complex system of processes that are concealed by the snapshot-in-time and surface appearance connotations of the word. Some processes are internal to crabs, such as respiration, digestion, and the Krebs cycle. Other processes are impossible to localize in the space and time of a crab snapshot. The adult coconut crab (Birgus latro) is evidence of a complex reproductive process, in which crabs mate and drop their eggs into the ocean on a rocky beach at dusk; the eggs exist as plankton, then as small hermit crabs; eventually some re-emerge on islands to grow into adult coconut crabs. They also interact with human processes, such as fishing, cars, and perhaps occasionally the deceased female aviator process.
Boxer crabs carry anemones in their claws and use the toxins in the anemones’ tentacles for defense; the anemones feed on the crabs’ scraps. The boxer crab process is inseparable from the anemone process. Wider processes are relevant to crabs as well, including the weather effects from long-term astronomical processes, ocean currents, asteroids, and evolution itself. Some processes are inseparable; others have limited interaction; some are completely separate, although subtle interdependencies are often hidden.
The physical shape of the adult crab represents the successful interaction of many processes. Carcinization is the process by which diverse non-crablike life forms adopt the shape of a crab – indicating that the crab shape is a kind of attractor, a particularly viable form given all the relevant processes within the system.
