We've been very lucky running into octopus recently. (I hope you're not getting tired of seeing them on the blog, but I can't resist them! They're remarkable animals.) And this one was demonstrating the best of its camouflage capabilities.
We'd never seen one mimicking coralline algae before. It was a beautiful pale pink coloration. And it was amazing to see how it had created the narrow white lines so often found in these segmented seaweeds.
It was a difficult setting for a photograph, with many reflections off the surface of the water, the octopus, and the algae. But here's another attempt.
And one more image — a close-up of an arm with the delicate patterning so similar to the adjacent coralline algae.
