Skin Tight

I stripped the skin of the sepia and it has a tiger look to it which acts as a camouflage. The one part of the body produces a light with special organs called photophores, (seen at the right of the photo) but at least two chemicals are required to produce bioluminescence. The first is known as a luciferin. This is the chemical that actually creates the light. The second chemical is called a luciferase and is the substance that actually catalyzes the chemical reaction. When these chemicals are mixed together light is produced.
