A casual attempt to catalogue the "iridistic" morph of the Eastern Red-backed Salamander, or individuals that visually have a higher-than-typical concentration of iridophores in the skin. Often easier to spot in the lead-backed morph.
Iridophores appear as tiny, shiny particles that catch the light. They may be silver or coppery in color.
