On dissecting the animal2 it was noticed that the intensity of colour increased, implying that in vivo some of the pigment is in a colourless, reduced form. Interest in the pigment was renewed by the demonstration of a tissue-pigment with a redox colour change in the isopod Crustacea3. The pigment…
