Fascinated by the fast color-changing nature of the squid’s skin, Tim and Greg from Backyard Brains connected an iPod nano to the squid’s fin nerve and played “Insane in the Brain” by Cypress Hill.

“The results were both interesting and beautiful.”

Backyard Brains explain that 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.

The video below is a view through an 8x microscope zoomed in on the dorsal side of the fin.
