Female squid have 2 ways to switch color, according to a UCSB study (EurekAlert)
The female common market squid –– AKA Doryteuthis opalescens –– may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle with rainbow iridescence. These flank a single stripe, which can go from complete transparency to bright white.
This marks the first time that switchable white cells based on reflectins –– the proteins responsible for reflecting light as color –– have been observed. The findings are published in the Journal of Experimental Biology.
