Not a bad job considering it’s gotta be most unnatural thing to camouflage against.

Alayne sends this site, The Pacific Northwest Tree Octopus, which begs the question, which is more endangered, the Tree Octopus or the Mountain Walrus?

But in wandering the page, the most interesting thing I found was real: a link to a study about cuttlefish and their abilities to camouflage themselves on the sea bottom (especially since they are colour-blind). The best bit? An absolutely stunning little Quicktime movie of a cuttlefish doing what they do best.
