Another awesome octopus story. If we die out, there's no question in my mind who'd take over.

This is a video of an octopus scooting around on land. Apparently they do this quite often. :D

That is wild. I wonder where it was.

Watching the video, I couldn't help but think of the Far Side cartoon, "Great moments in Evolution."

I wonder why it came out of the water?

Can octopi hold their breath? I can't even picture lungs on a octopus.

Gah. I spelt Octopus wrong in the thread title.

Anyway, this page has the same video but answers your questions too:

Swift: Fitzgerald Marine Reserve in California
Salty: To hunt, or possibly to escape
Solfe: They need their skin to remain moist

I, for one, welcome our new cephalopod overlords.

Is anyone else nerdy enough to think of "Crash on Volturnus" while watching that video?

i think that there will be a war for global domination between the octopi and dolphins when the human race isn't around any more. i think it will come down to whichever species can figure out how to live on land for lengthy periods of time..

I was thinking of Squibbons, myself.

I knew they could leave water for short periods of time, but that's the first video I've seen of them doing it. Crazy. :) I doubt they can breathe air, but maybe (just like fish and people) they can store enough oxygen in their tissues to survive topside.

I wonder if a niche for terrestrial octopi could ever open up; it did, after all, happen for land crabs...

Really, looks fine to me. ;)

What makes you think they'll wait until we die out? They're already conquering the trees (http://rationalwiki.org/wiki/Conservapedia:Pacific_Northwest_Arboreal_Octopus)!

Octopuses, like other cephalopods, breathe with gills. That means they cannot survive on dry land for a long time. But they can stay there for a short period of time, which they use during low tide to hunt in tide pools.

Why would dolphins want to come out of the water? They just spent millions of years evolving to get back in the water after coming on land millions of years before.

to gain a tactical edge over their squishy 8 legged enemies..

Nice video, though the audio track is annoying.

I was holding my breath and cheering for the poor sucker to make it back to the water alive.

Thanks Swift.

Octopi would win easy. Dolphins can't throw spears.

If you have a video of an octopus throwing a spear I will give you a dollar.

Haven't there alread been plenty of incidents of octopi escaping their enclosures at aquariums?

Cool to watch though.

I, for one, welcome our new cephalopod overlords. So does PZ Meyers.

Half-seriously, it's probably a good thing for us they only live a couple of years!

Wasn' tthere a Hal Clement story written from the point of view of a civilization of intelligent Octopi?

Wasn't that about the totally fictitious intelligent Kilopi?

I saw a similar documentary, where the guys in an aquarium were perplexed as to where their sharks were disappearing. They installed cameras and lo and behold the tentacled ones were munching on the sharks. That was easy they figured, they then removed the octopus (it a large specimen) and put it in its own tank,....(dramatic music).... the octopus climbed out of his tank and went to snatch one shark and climber right back into his new tank. It was funny and scary at the same time.

Yeah, one researcher had a casualty in her office. One octo with a healthy dose of ambition managed to unlock its tank (locked after the THIRD successful escape) and climb a shelf before dying.

For the shark, I presume it was scary rather than funny. :)
