Two populations of iridophores are responsible for the iridescent color of the squids Loligo pealii and Loligo opalescens. The superficial group, the short iridophores, underlie the chromatophores and are associated with muscle cells of the skin. The long iridophores, a deeper-lying group, are arranged in a dense sheet. The ultrastructure of iridophores was described, including iridosomes, iridosomal platelets and iridosomal tubules. The observations were discussed in terms of adaptive coloration in these animals.
