True colors: Female squid have 2 ways to switch color, according to a UCSB study

Researchers at UC Santa Barbara discovered that female common market squid possess two distinct systems for reflecting light: Bragg reflection and Mie scattering. These systems allow the squid to switch between transparent and white colors, with the latter appearing as a result of condensation and dehydration of reflectins-based proteins.
