Squid's membrane goes insane while listening to Cypress Hill AUG 24 2012
The crazy (and possibly high) folks at Backyard Brains hooked an iPod up to a squid in such a way that when the music played, it was converted into electrical impulses that triggered color changes on the squid's skin, thereby creating the world's first cephalo-iPod. Here's a video of the squid's skin pulsing along to Insane in the Membrane by Cypress Hill:
During experiments on the giant axons of the Longfin Inshore Squid (loligo pealei) at the Marine Biological Laboratory in Woods Hole, MA; we were fascinated by the fast color-changing nature of the squid's skin. Squids (like many other cephalopods) can quickly control pigmented cells called chromatophores to reflect light. The Longfin Inshore has 3 different chromatophore colors: Brown, Red, and Yellow. Each chromatophore has tiny muscles along the circumference of the cell that can contract to reveal the pigment underneath.
