WATCH: What Happens When A Squid Listens To Cypress Hill

Posted Aug 27, 2012

Squids do not have ears.  However squids to react to electrical signals.  In this experiment, a squid’s fin was hooked to an electrical signal which was converted by the audio signal of a Cypress Hill song “Insane In The Membrane.”  Backyard Brains put together the viral video below of the experiment that they did at the Marine Biological Laboratory in Woods Hole, Massachusetts.  Check out the video below:

The video is a view through an 8x microscope zoomed in on the dorsal side of the caudal fin of the squid. We used a suction electrode to stimulate the fin nerve. Chromatophores are pigmeted cells that come in 3 colors: Brown, Red, and Yellow. Each chromatophore is lined with up to 16 muscles that contract to reveal their color.
