Squids are mysterious creatures roaming seas and oceans. They are also the subjects Urs Albrecht chose for his winning picture in the Swiss Art + Science competition, “One Out.” The photo shows squid juveniles, one of which displays striking colors in opposition to the rest. The bright individual is also physically removed from the group, may be scared or angry. The image is fascinating because we can see complex biology at play with the naked eye. Squids are Coleoid cephalopods, mollusks with arms attached to their heads. They have lost their shell and developed larger and highly differentiated brains and camera-type eyes through evolution. Their nervous system is highly organized. The central brain acts as the decision-making unit, and the peripheral nervous system processes motor and sensory information.
