Truly a great find yesterday while tidepooling at Davenport Landing, Octopus rubenscens, the red octopus! Watch closely and you will see that it’s spotted appearance mimics the bits of shell that are adhering to the sea anemones in the background. The spots disappear for a moment and the body develops a deep red hue as it passes over a patch of purple urchins then quickly develops the molted spots as it nears the shell laden anemones again. Incredible.
Octopus are masters of disguise and accomplish their pigment changes using chromatophores,1000’s of color cells that are embedded in their skin. By expanding or contracting these sacs of pigment they can instantaneously alter their color to match their surroundings. They may even morph the texture of their skin to mimic algae, rocks or coral.
