Iori Tomita, a Japanese artist, combines art and science by turning the flesh of marine life transparent. And to enhance each creature's invisibility, he injected dye into their bones too. It's a pretty psychedelic combination.
How do you make flesh translucent? It's a method that involves the dissolution of natural proteins. Tomita first learned of it from scientists who would examine the minuscule bone structure of fish. He then adds red dye to hard bones and blue dye to soft bones, which would blend together if the skeleton was complex enough. Depending on size, it takes 4-6 months to reach Tomita's intended effect.
