Squid changing color - not just for octopuses!

Squid can change their colors too - not only octopuses and cuttlefish.

Science Alert: Octopuses and cuttlefish are the ultimate wallflowers. By changing the patterns and colors of their skin, these cephalopods can slip into the background of almost any seafloor scene.


Squid, in comparison, are usually translucent or iridescent, but that doesn't mean they don't have a colorful trick or two up their eight sleeves.

Recently, scientists in Japan were surprised to find a species of oval squid raised in captivity could change its coat, depending on whether its tank was clean or covered in algae.

According to the authors, it's the first time a squid has been caught camouflaging against a background under laboratory conditions.

What do they mean “ Recently, scientists in Japan were surprised to find a species of oval squid raised in captivity could change its coat, depending on whether its tank was clean or covered in algae.”…are they students, because I saw this described and demonstrated in 88 in my marine biology class in Hawaii….then we dissected it….then we cooked and ate it as a class. Interesting teacher.

Absolutely not the first time they’ve been “caught” doing this…maybe the first time with high definition cameras, in one specific laboratory condition, with that specific species, raised in captivity, but this is every day behavior for many cephalopods, including squid, and absolutely not a new discovery.

Let’s see them decipher the intense flashings, strobing, color waves, slow fades, etc that they use to communicate and hunt. That might be a first….but I doubt it. Others have studied their insane chromatophores and their amazingly mailable mantles and how they use them for decades if not longer.

This is a neat bit of biology, but to pretend they just discovered this is outrageously dishonest. Get real, people knew squid camouflaged themselves amazingly well long before that guy named Jesus was fathered by a forced pedophilic inception. Almost like saying scientists just discovered newts like it moist, or that water is wet.
