Wearing a giant squid video camera, the scientists found the animals ability to flash and flash - their skin color changes at different speeds. Biologists believe that these signals shellfish communicate with each other and attract mates.

Giant Peruvian squid (Dosidicus gigas) grow up to 1.8 meters in length, and are very aggressive man, when trying to lead them monitoring shellfish divers tore off the mask and attacked the camcorder. However, ocean scientists from Stanford University were able to establish special chambers Crittercam on the trunk itself squid. Scientists have adapted to this children's swimwear, tying them so that the fins, tentacles and catching cephalopods hands remain free.



As a result, scientists were able to observe the communication squid in the sea. Most of them struck by a previously unknown behavior strategies: clams quickly changed color from red to white. According to lead author Hannah Rosen (Hannah Rosen), so animals attract potential mates (not in vain in the first part of the video squid touch each other of course).



In addition, the shellfish can rapidly flashing camouflaging its presence - they change color in response to changing rays of Sunlight penetrating into the water column.



Scientists have figured out how to get squid to change color: they are forced to shrink chromatophores - a pigment and reflective cells responsible for skin color in cold-blooded animals. Flashing and blinking chromatophores trigger the nerves of the central nervous system - about the same as the human brain sends signals to the hand, causing it to move.
