The first image shows a copepod, a tiny aquatic crustacean about 1 mm in size. It feeds on algae, yeast, bacteria, etc. It is therefore a so-called filter feeder.
In the second image, this food chain hierarchy has been reversed—we can see PSB (purple sulfur bacteria) and slime molds feasting on the dead shell of the copepod. Strangely enough, this scene of death and decomposition does not seem repulsive or terrifying at all; on the contrary, I found it beautiful and fascinating. In my opinion, the appearance of the second image thus contrasts with its inner meaning, and perhaps it is precisely this tension that adds to its impact.
Another reason why this work makes a very strong and personal impression on me is the fact that I, too, will one day end up exactly the same way as this bivalve.
