Wallpaper Calendar

For each month in 2024, we will post a wallpaper calendar for you to download to give your desktop a fresh look. At the end of each month, the image will be retired to the wallpaper collection without the calendar.

Cephalopods, including squid, octopods, and cuttlefishes, change color to communicate (with potential mates or possibly to warn predators) or to camouflage and disguise themselves. They do so using color-changing cells called chromatophores. Movement of muscles surrounding these elastic pigment sacks causes them to expand (revealing more color) or retract (less color). We saw this squid off North Carolina. Learn more and watch it demonstrate its color changing abilities in the corresponding video.
