I distinctly remember seeing an exhibition of this work in Los Angeles in the early aughts. For the life of me I can't remember where. The photos were shot with a macro lens and blown up so that each specimen was ... 12" square? maybe bigger?

Even then there were dozens upon dozens of them on display. It was mind bending.

If you're into this sort of thing I can highly recommend the parasite museum in Tokyo https://www.kiseichu.org/e-top
