I've been reading this blog too much. My first response to this picture was "aawww...how cute!"

Is the grayish blue in the (skin between the tentacles, which I don't know the name of) normal or a function of being...gulp...no longer among the living?

While I can't state conclusively that the octopus is alive (not being a marine biologist,) I can say that the bluish tinge to its tentacles do not imply anything much about its health. For one thing, octopi (or is it octopuses?) can change the color of the skin. For another, underwater photography can be very tricky. The first color to filter out at any depth is red, followed by yellow. It may be that the true color is uniform, but the camera's flash failed to fully illuminate the subject.

I'm with Dianne. What a beauty!

It blends very nicely with the rocks. (Yeah, it's cute!)

Well, that didn't work! I used a less-than sign and a 3 to indicate a heart, but it tried to format it.

Anyway. We love cuddly octopi:

Hi Laura!

It's gorgeous. It reminds me of Gustav Klimpt's paintings, only even more beautiful, infused with glittery light.

There's an interesting article in the local weekly (Metro Silicon Valley) about the spread of the Humboldt Squid north along the N. California coast in the last several years. A PDF including the article is at http://www.metropdf.com/0613_MT_1_front.pdf

That is a classy looking 'pus.

Great cephalopod!

Anyone catch Stephen Colbert last night? He said Soledad O'Brian couled be part cephalopod! Made me think fondly of the Friday cephalopod I'd see today.

That Caribbean reef octopus video is fabulous Clinton. Thanks for sharing.

excuse my ignorance, but my first thought was- how is the octopus surviving on a rock, out of the water, but other people have now suggested that it is perhaps dead, or the photo was taken underwater.

so I was wondering if PZ could give a few more specifics about this photo, and also generally, do cepholopods ever spend time out of the water, on rocks and suchlike, or is that a silly think to wonder?

Toby, they can stay outside of water for a little while. My friend who used to volunteer at an aquarium in California told me about a mystery there--lobsters were disappearing out of their tank overnight with no sign of what was happening to them. The staff set up a camera in the room to find out what was happening, and found an octopus across the room was raising the lid on its own tank, scuttling across the floor, reaching into the lobster tank and having a treat, then scuttling back across the floor and climbing back into its own tank.

My favorite part of the story, though, was that, after it was back in its own tank, it was pulling its own lid back down! Maybe it just remembered that as part of the process, or maybe--I like to think, anyway--it was throwing anyone who came in the next morning off its track. Pretty intelligent, either way.

Toby,

Having seen a lot of octopi underwater I'm quite confident saying that the octopus in question is alive and in the water. Most likely the camera was underwater too though I suppose it's possible the animal was in a tank or shallow pool.

Some octopi do occasionally wander out onto land. I think at least one major aquarium had trouble with one that went wandering around at night from tank to tank sampling the delicacies in the other exhibits.

I just found a BLOG all about SQUID!! This is not an April Fool's joke. I can tell you how I found it but it would be embarrassing... since the site where I found the link is all full of puppies and kitties and cute stuff... Heh. It's at http://squid.us/

OK, well, you already knew about that one. Or they knew about you. Back to the drawing board. :)

thanks for the responses to my questions. that story about the octopus and the lobsters is awesome!

its octopusses not octopi,
yes hes under water,
its at night cause octopusses hunt at night hence the bad lighting
