Well, they probably get annoyed.
Cephalopods have a nifty trick where they can change color by altering the size and shape of chromataphors, or “colored cell thingy blobs”. Like most cells, these chromataphors react to electricity in different ways. Mainly, expanding and contracting.
The folks at Backyard Brains, a group that does neuroscience at home, have decided to run an experiment where they pump the signal from Cypris Hill’s song Insane in the membrane right into the nerve on a fin of a squid to see how the chromatophrs react. Not surprisingly, they pulse to the beat.
Just because it isn’t a surprise, doesn’t mean its not fun to watch.
