Different wiring for squid's iridescent and pigment displays

摘要

Squid iridescent displays are mesmerising – and mysterious. ‘Squids are the only invertebrates known to exert neural control over their iridescence,’ explains Trevor Wardill, ‘but we still don't know for certain why they use iridescence, and which specific neural pathway is responsible for iridescence control.’ To shed light on these questions, Wardill teamed up with Paloma Gonzalez-Bellido and other colleagues at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, to take a closer look at how and why squid create their stunning visual displays (p.850).
