Humboldt squid use bioluminescent organs and changing skin tone patterns to communicate with each other in the dark

A new study suggests that the dark sea does not prevent communication between Humboldt squid,media CNET reported. These organisms can use bioluminescent organs to visually “communicate” with each other. The researchers say they can communicate accurate information by changing skin tone patterns, which can be translated into warnings such as “don’t touch my food.”

Dosidicus gigas use their bioluminescence organs to make the whole body glow, but researchers at Stanford University and the Monterey Bay Aquarium Research Institute (MBARI) have found that this also creates a backlight for changing the color pattern on the skin – just like words on an e-reader screen. The researchers believe the creatures use these changes to send signals to each other in deep water, and their new findings were published March 23 in the Proceedings of the National Academy of Sciences.

Benjamin Burford, one of the lead authors of the paper and a graduate student at Stanford University’s School of Humanities, said in a statement. “Perhaps they need this ability to glow and show these pigmentation patterns to promote group behavior in order to survive there. “

MBARI’s remote-controlled unmanned submersible captured images of Humboldt squid, which live 870 to 2,750 feet (266 to 838 meters) off the coast of California. The researchers identified in the video for the behavior of squid that alter seditadopatterns on the skin to convey signals.

Interestingly, the researchers also believe that squid communication can even “break down into different cells, and the squid will regroup different pieces of information, similar to the letters in the alphabet.” However, the researchers say it’s too early to say that squid communication is as complex as human language.

“We sometimes think of squid as a crazy life form living in this world, but we have a lot in common – they live in groups, they interact with each other, they talk to each other,” Burford said. Studying their behavior and that of other inhabitants of the deep sea is important for learning how life lives to live in an extraterrestrial environment, but it also tells us more generally about the strategies used in the extreme environment sonons on our planet. “
