Friday Squid Blogging: Chromatophores – Schneier on Security

Friday Squid Blogging: Chromatophores


Chromatophores are tiny color-changing cells in cephalopods. Watch them blink back and forth from purple to white on this squid’s skin in an Instagram video taken by Drew Chicone…

It’s completely hypnotic to watch these tiny cells flash with color. It’s as if the squid has a little sky full of twinkling stars on its skin. This has to be one of the coolest looking sea creatures I’ve seen.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
