Friday Squid Blogging: Humboldt Squid Backlight Themselves to Communicate More Clearly
This is neat:
Deep in the Pacific Ocean, six-foot-long Humboldt squid are known for being aggressive, cannibalistic and, according to new research, good communicators.
Known as “red devils,” the squid can rapidly change the color of their skin, making different patterns to communicate, something other squid species are known to do.
But Humboldt squid live in almost total darkness more than 1,000 feet below the surface, so their patterns aren’t very visible. Instead, according to a new study, they create backlighting for the patterns by making their bodies glow, like the screen of an e-reader.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
