Octopuses pick nearby landmarks to copy for their camouflage more than trying to blend into the general area; image courtesy of Keren Levi The octopus is an amazing master of disguise. It can essentially vanish, right before your eyes, into a complex scene of colorful coral or a clump of kelp waving in the currents.
For a view of this phenomenon in reverse, check out this now-viral video shot by Woods Hole Marine Biology Laboratory senior scientist Roger Hanlon. The clip reveals how entirely the octopus was camouflaged before it was startled into jetting away—to the inevitable oohs and ahhs of the audience. How do these invertebrates manage this quick-change feat? A new paper, published online last month in PLoS ONE, suggests that octopuses do focus on a limited selection of nearby objects in order to determine their disguise.
