[...] the Sea Hare is the name that is commonly used to specify a type of mollusk, of the sea slug kind, that exists all over the world in many different variations. Most sea hares have a soft, internal shell made out of protein, that is believed to be a remnant organ given the fact that is absent in some of the species genera such as the Stylochelius and the Bursatella. Biologists believe these animals have stopped relying on the weak protective layer in favor of adjusting to their environment—by developing a form of camouflage resulting from their food digestion, as well as glands with secretion abilities (such as ink, like the octopus).
I became interested in Sea Hares after coming across a video of one swimming;
This is quite the peculiar sight: the flamboyant movement seems to lead the creature nowhere, you could say it is failing as a means for locomotion, especially since it is also able to crawl the sea floor in the shallow waters where it lives. At the same time, it is exposing its gill and mantle: the juicy insides its no-longer needed shell once set out to protect.
This contradiction that the creature is performing I understand as an embodiment of a type of creativity driven about by the death instinct. The same instinct that led the singular cell to find shelter in the inorganic shield.
Throughout this talk I’ll be looking at more ways in which this creativity finds solace, as I’ve attempted to before when looking at Parasitism. As another type of inconsistency defending both life and death, parasitism, a type of symbiotic relation between two beings, opens up the realm of what defines an organism—the threshold of demarcation, separation and distinction between the two is challenged, with the beings assuming more and more of an ambiguous position throughout their co-existence.[...]
