Dynamic pigmentary and structural coloration within cephalopod chromatophore organs
https://doi.org/10.1038/s41467-019-08891-x We report the discovery of structural coloration emanating in precise register with expanded pigmented chromatocytes. Concurrently, using an annotated squid chromatophore proteome together with microscopy, we identify a likely biochemical component of this reflective coloration as reflectin proteins distributed in sheath cells that envelop each chromatocyte.
