Cuttlefish biological mechanisms baffle scientists

Cuttlefish utilize complex biological mechanisms to change their skin patterns and textures, a process that continues to intrigue scientists. These cephalopods use specialized structures in their skin to manipulate color and light.

Chromatophores contain pigments, while other structures assist in reflecting and scattering light. Beyond color, some species can alter their skin's surface texture using small muscular protrusions. Research involving Harvard and the Marine Biological Laboratory (MBL) has identified the role of reflectin proteins—previously known for creating iridescent colors—in helping the skin maintain its appearance as its components expand and contract.
