Octopus Hijinks!

Nature is amazing. "Camera approaching coral with no sign of animal. As the camera gets closer, an O. vulgaris that was camouflaged changes color to white and becomes visible." This page leads to a video clip containing "special effects" that put the movie industry to shame. (via Looka!)
Wow. I had to freezeframe before I could believe it. Amazing!

Damn. I love Octopuses, but can't believe this is real. Their camouflage is good, but I don't think they can pull of different perspectives so greatly.
Especially suspect to me are the spikes on the lower right part of the angle. They seem to protrude into the water, then melt back into the main body. They don't have control like that, and wouldn't most cephalopods like this just ink and run, not just appear when something (like this camera) gets close? They're not brave, and wouldn't show themselves to intimidate anyone.
Or is my skepticism running over?

Busithoth: Look at the beginning of the video. The "genuine" part of the plant/coral is moved quite a bit by the water. The area from which the creature emerges remains completely still.

I have to agree with Busithoth, as amazing as it looks.. there are some oddities, notably with the parts of the "coral" that just sorta retract into the body.
Either way, after wandering about the page to se how legit it really was, I did find a nother really cool video Three S. Apama hovering in front of rocks in courting display with color clouds moving along body and arms

On a lark I plopped the observers name into google, and conspiratorially enough the first returned link was for a Roger Hanlon, digital manipulator.. except it was some guy and a copy of photoshop.. and of course the remainder of the links was for a Roger Hanlon, marine biologist, investigating cephalopods.

Sure they can. I've seen cephalopods do much more impressive color-shifting allatime on the tv.

Actually, octopuses/pi do have some control over their skin texture. ISTR that it varies by species though.

It would seem that if it were fake, it would have been an awful lot of trouble to go through for a little university-housed cephalopod database, you know? I can't really imagine what the gain would be.
But yes, watching it frame by frame makes it much more clear as to what changes happen.

The spikes are behind the octopus, and appear to "retract" as the octopus moves in front of them. At least, that's how I see it.

I don't think the coral in the bottom right is moved in; I think the octopus is moving/getting bigger, covering the coral. I don't think it's fake, though I'm certainly no expert. Either way, pretty damn cool.

I'm actually a cephalopod.
Though I was born to seemingly normal parents in Stirling, Scotland, I always knew that there was something special about me. First of all, I was an octopus. My eight legs wriggled while other kids boldly strided back and forth to the slide. I sat on my swing like a lump of jelly while Irma and Chuck swung higher and higher, giggling. While they enjoyed tacos and played mandolins, I prodded at oatmeal, nudged saxophones.
I gradually came to terms with my body, experimenting during adolescence with drugs and sex. My first inking incident was an acute embarassment - to my girlfriend of the time, more than to myself - but these early traumas were eventually forgotten. The one intuition I couldn't shake, however, was that I was different.
Shortly after I graduated from college with my Lit degree, I confronted my parents about my semitranslucent skin, my globule eyes.
"I'm not a human!" I cried, voice shrill and flatulent.
"Of course you are, honey," said my mum. Her voice was cracking, her eyes glazed-over. She glanced at my father.
"You're a human on the inside, Sean." He patted me on the top of my head. It made a flat, squelching sound.
"But that doesn't matter!" I gurgled. "For twenty years I've told my friends that I was simply born with a disability, that my appearance was the result of juvenile jaundice. But now I learn that that's not true! I'm not even a person!"
"You're our little person," said my mum, quietly.
"That's not enough," I said in a soft, trembly voice. "What am I really?"
"You're a cephalopod," said my dad.
"Arlen!" yelped my mother. Her lower lip began to tremble.
"Well he's got to learn sooner or later."
- - -
I visited the Falkirk library and made a bee-line for the librarian.
"Do you have any books on cephalopods?" I asked.
The librarian blanched, mouth twisting into a disgusted tentacle. "What are you?"
"Precisely," I said.
The only book in the stacks was E.W. Williams' classic The Seven Seas: a Taxonomy. Williams, the grandfather of popstar Robbie Williams, examined six or seven cephalopods in his chapter on coral symbionts. Learning about my biological cousins, twinkles of pride began to bloom inside me. I felt my ink inside my skin, and a wave of warm passed over (what I later knew as) my chromatophores.
Moments later, a young woman approached me, running briskly down the aisle. She had a leather jacket on, held tightly shut with her hands. And then - paf! - as her foot slipped under me and caught, she went tumbling to the floor, and from out of her jacket burst a half-dozen tomes: Anne McCaffrey novels, mostly, but also Hesse's Siddhartha and Althum Buxley's Mozart and Amelia Earhart: Simon of Aramathea's Contemporary Legacy. We were soon joined by a librarian and a security guard, who cuffed the crumpled book-thief.
"What the fuck did I trip over?" asked the glowering guttersnipe.
It was then that I realized that I was the colour of the floor.
The discovery of my colour-changing abilities not only gave my life a renewed sense of worth, but it kick-started my career in law-enforcement. Though Scotland Yard was initially dubious, sufficient evidence convinced them that land-roaming octopuses were not in fact particularly rare, and that my life-story could be trusted. I climbed the force quickly, gaining the affectionate nickname "Chipper."
Following a coral injury in 1987, however, I retired from police-duty. I did not miss the stressful workplace, the morally vacuous tory-voting inspectors, but the departure left a void in my life. While completing an M.A. in Art History, I began to work on the side as a marine lobbyist, trying to push through a grammatical amendment for the powerful Bathypoylpus Articus Foundation (which has quite an interesting pedigree, incidentally, founded during the Blackstead Riots of 1947, in a response to encroaching political sway by cuttlefish and lobster-dog interests). Within eighteen months, the Octopuses Act (UV 11341) had been enacted, and no more grammatical atrocities would be committed upon the Cephalopoda class; as our campaign slogan went, "Goodbye goodbye Octopi! Go Octopuses - just ask the Missus!"

cephalopods are crazy, they have way too many "features". they can change their texture as well as color, using papillae. they can create spikes, or rough textures like rocks and things. disturbing but true. i'm not saying the spikes are definitely part of the octopus in this video, but they do have that ability. they also have ink, which is odd, large brains, they move using water in the same way that jet engines use air.
they're also really smart too. here's a fun book.
and their underwater cities are fantastic.

This is why I loved watching nature shows as a kid -- who needed crappy sitcoms when the really cool stuff was all real?
And I thought the plural was Octopi, having taken latin in school (boy, I was a dork, huh? nature shows and latin. no wonder I didn't have many friends!). Didn't realize it was from Greek. Thanks, Marquis.

I once saw this really cool documentary on an Indonesian Octopus that would mimic other fish to attract prey or drive off predators:
Australian researchers recently announced their discovery of an octopus in Indonesian waters that, when threatened, takes on the appearance of poisonous animals. For instance, when territorial damselfish pester a foraging octopus, it takes on the appearance of a banded sea snake, which eats damselfish.
This octopus can also transform itself into a lionfish with bannered, toxic spines extended. If that doesn't suit the occasion, the octopus can mimic the banded sole, a flatfish species common in the area also bearing poisonous spines.
How does a spineless octopus transform itself into the shapes and colors of such diverse creatures? Ingeniously. To look like a sea snake, the octopus hides six of its eight arms inside a hole in the sand while stretching the remaining two in opposite directions. Then the octopus changes color to match those of the snake.
To resemble a flatfish, this octopus uses jet drive. Propelling itself forward with head extended, the creature molds its trailing arms into the leaflike shape of a sole. The octopus then undulates its body along the bottom like a swimming flatfish.
Check out some photos here.

This video caused my entire office to shut down for about ten minutes while everyone on my floor debated its authenticity. The verdict was that you can tell it's real because you can see the contours and the eye of the octopus long before it changes color, and the when it "appears", it appears precisely along those contours.
Either way, it's teh cool.

I can't find the reference -- I remember seing a video on the web of an octopus (maybe a cuttlefish?) that swims a foot or so off the sandy ocean floor looking for prey. It emits bioluminescence in such a way as to completely eliminate its shadow, so as not to alert potential prey. Way cool.

I think if you look closely, the "protruding" pieces might just be a matter of perspective on the pattern the little guy has on its skin. If you play the clip very slowly you can see the colours changing. I do think this clip cuts off about .03 seconds before a nasty explosion or something similar filling the camera lens.

PBS just had on a Nature episode about Octopus that was great. I've seen a lot of programs about octopus, but was floored by the footage in this one of the Giant Pacific Octopus at the Seattle aquarium that caught and killed several sharks in it's tank. Apparently keepers would come in to work in the morning and find a dead shark, but couldn't figure out what was happening to them. So someone stayed overnight and caught the octopus on tape. Amazing animals.
