Seen here trying on a hat, this is a video from PBS documenting a decorator crab's efforts to disguise itself by sticking pieces of seaweed and algae to itself, using its natural velcro (rows of stiff, hooked hairs) to keep the pieces in place. Nature: isn't it amazing? You know just yesterday I saw two hummingbirds boning on a branch outside my bedroom window and I thought to myself, 'Damn, that was quick.' Maybe not as quick as me, but I've never had a lover who wasn't disappointed. I've also never had a lover who wasn't pleased. I've never had a lover, that's what I'm saying.
Keep going for the fascinating video.
Thanks to Dub, who agrees the best camouflage a sea creature can have is a shark costume.
