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

Article on this topic published in the journal of Experimental Biology, and briefly about the study informs Daily Mail.

Huge Peruvian squid (Dosidicus gigas) grow up to 1.8 meters in length, and are very aggressive to humans: when trying to lead them research clams tore divers mask and attacked the camera. But marine scientists from Stanford University have managed to establish specialized camera Crittercam on the body of the squid. Scientists have adapted to this baby bathing suits, tying them so that the fins, tentacles and trapping hands cephalopods were left free.

As a result, scientists were able to observe the communication squid in the sea. Most of them struck a previously unknown strategy behavior: mollusks quickly changed the colour of the skin from red to white. Taking into account the opinion of the principal author Hannah Rosen (Hannah Rosen), therefore animals likely attract mates (no wonder in 1 part of the video squid touching each other extremities).

Also, molluscs able to flash quickly, camouflaging their presence - they change color according to the changing rays of sunlight penetrating the water column.

Scientists have learned how the squid is obtained to change the color: they are forced to shrink the chromatophores from - pigmentaria and reflective cells responsible for the coloration of skin in cold-blooded animals. Vspuchivanie and flashing chromatophores trigger the nerves of the Central nervous system is roughly analogous to how the human brain sends signals to the arms, forcing her to move.
