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.
