Something strange is happening to the oceans. As coral reefs wither and fisheries collapse, octopuses are multiplying like mad. As soon as they perceive weakness, they will amass an army and invade the land, too.
Dicyemida might get the award for strangest possible lifestyle. Not only does it only live in guts of cephalopods, it has two different modes of reproduction, which it deploys strategically through its life cycle.
Cephalopod experts at UC Berkeley have discovered that the larger Pacific striped octopus—seen here outstretched—employs a rare hunting strategy. Instead of pouncing on its prey with all eight arms (a common technique among octopuses), it extends a single limb, like a grabby toddler, and startles its prey into…
Southern dumpling squids (Euprymna tasmanica) are natives of shallow, sandy Australian sea beds, and their small, squat bodies and huge eyes combine to make them one of the most frickin-adorable animals on the planet. They spend their days hiding under the sand, but at night they’re tenacious lovers.
These adorable creations are from Kirstie Williams' etsy shop CuriousCephalopods, where you can also commission ones in any color you wish. Not only are they awesome — look at those tentacle curls — I am counting on one to provide protection from nature's most intelligent sea creatures.
Deep-sea researchers led by Robert Ballard (best known for his 1985 discovery of the Titanic wreckage) have caught a rare, extended look at an uncharacteristically jumbo dumbo octopus, with the aid of a remotely operated vehicle (ROV) in the unlit depths of the Caribbean sea.
To look for aliens, most people peer towards the sky. But if you look down, you'll discover they already live among us. These aliens have brains, like we do, but they're mostly inside their arms, and each arm acts as if it has a mind of its own.
It's seafood for breakfast in the home of Nathan Shields. Octopuses, squids, cuttlefish, and even a few extinct critters have found their way onto his kids' breakfast plates. It's an adventure in taxonomy and cookery, all at once!
From the entryway to the Institut Océanographique in Paris comes what might be the most awesome sculpture to adorn an archway in the history of sculptures and archways. Also Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn.
Architects frequently take their design cues from nature, but while some prefer the curves of budding flowers or the sturdy power of desert mesas, others give their buildings reaching tentacles, high, squid-like towers, or the occasional smattering of what looks like suckers. Here are a handful of buildings and design…
Octopuses are absolutely hilarious, what with their penchant for puzzle-solving and infinitely useful tentacles. Just check out this video by Lauren De Vos of the University of Cape Town's Marine Research Institute — while filming a bait canister in Cape Town's False Bay, a thieving octopus managed to undo the humans'…
Cephalopods like squid and octopuses change their appearance with color-changing cells called chromatophores. Chromatophores can be stimulated via electrical signals — like the ones coming out of the headphone jack of an iPhone playing Cypress Hill's "Insane in the Brain."
Nobody envies the sex life of a male Australian giant cuttlefish, also known as Sepia apama. The largest cuttlefish on Earth, these cephalopods typically mate only once in their lives and outnumber females 11 to 1 — which means they have to spit some serious game if they want to get any.[ via ]
Researchers have shown that ink sacs from a cephalopod that lived 160-million years ago still contain traces of the pigment melanin. That's an impressive find in its own right, but what really floored the scientists was how familiar these pigments looked.
Dive into murky water, thrust your hand into a hole, and return to the surface with with an octopus. Octopus wrestling sounds like a horribly rude form of aquatic home invasion. But let's time travel back to the Pacific Northwest circa 1960, when this was a popular spectator sport.
This video uses your eye's built-in blind spot to trick your brain into making a man's head vanish. I've seen some pretty awesome optical illusion videos in my time, and I'm calling it now: this is the best one yet.
We love ourselves some mimic octopodes, and they certainly love each other. In fact, here are two Indonesian mimic octopodes engaged in the delicate art of making genetic knock-offs of themselves. Such choreography! This is some tentacle porn we have no compunction posting without the NSFW tag.
