Phenolases in the Echinoid, Diadema antillarum Philippi


Diadema antillarum possesses an abundant black pigment which shows the chemical and histochemical properties of melanin, and is concentrated in epidermal chromatophores1. In view of much evidence from other forms of a relationship between the occurrence of melanin and phenolases, evidence of such enzymes in Diadema was sought.
