These see-through critters are preserved in jars and injected with amazing technicolor enzymes to make them all glow-y. Break it down, Science: “Tomita uses an enzyme to dissolve the natural proteins in the flesh. He then injects red dyes into the harder bones and blue dyes into the softer cartilage, thus highlighting usually unseen internal structures. The dead creature is then preserved in a jar of glycerin”. You can even buy miniature versions of these… in Japan.
"Originally, the method of making transparent specimens enzymatically turning the protein transparent, dyeing the bones magenta and dyeing the cartilages blue was established for scientific purposes to study the skeletal system. Taking this a step further to refine the form and coloration of the specimens requires time and experience. I create transparent specimens as pieces of work that help people feel closer to the wonders of life. People may look at my specimens as an academic material, a piece of art, or even an entrance to philosophy. There is no limitation to how you interpret their meaning. I hope you will find my work as a "lens" to project a new image, a new world that you've never seen before.
