Wow. This is amazing. I knew cuttlefish could change their hue to blend in with the sea floor and protect themselves from predators. But I didn't know they could use that skill to create trippy light shows that put their prey into trance.
Giant cuttlefish have some unusual mating rituals. But once they find a suitable partner, the act of knocking boots (er, tentacles?) is kind of incredible to watch.
Underwater craft have come a long way since Bond drove that Lotus into the sea, but even today, they still have problems: conventional propeller-driver robots get tangled on underwater obstacles like seaweed and rope, and the noise confuses the cute little dolphins who use vibrations to navigate. That's why this…
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!
Plenty of superheroes and supervillains are animal themed, taking on the grace of a cat or the strength of a spider. But there are animals who are super in their own right, with abilities perfectly suited to saving the day.
Cuttlefish always seem to be among the most fascinating marine life forms — whether it's on account of their flashy battles for mating rights, or their ability to see the world through polarized light. And now, researchers have discovered yet another extraordinary thing they can do: Male cuttlefish can alter their…
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.
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.
The animal kingdom is brimming with fauna who get their rocks off in surprisingly unorthodox ways, and it adds an extra level of curiosity when you depict these behaviors using anthropomorphic models. Illustrator Humon has done just that. Oh hyenas, giving birth through your positively epic clitorises and whatnot.…
Cuttlefish are among the most remarkable of cephalopods, but nobody expected the creatures to have this particular trick up their sleeve. Cuttlefish can actually see information in the angle of intense polarized light that we can barely comprehend.
If you don't have tickets to Laser Floyd at your neighborhood planetarium tonight, just watch 199 seconds of Metasepia pfefferi — a.k.a. Pfeffer's Flamboyant Cuttlefish — creating its own variegated light show. Some of you may tempted to lick these creatures and pop on some Jethro Tull, but that's not the best idea,…
In this excerpt from the BBC/Discovery documentary Life, we learn about a mating strategy that's fairly common in the animal world. A female cuttlefish is courted by two males. One is large and dominant, fighting off other males in order to fertilize the female's eggs. The other is what's known rather judgmentally…
As far as invertebrates go, you don't get much smarter than the members of the mollusk phylum, which includes octopuses, cuttlefish, and squid. But mollusks apparently didn't think through their evolutionary path very well, developing brains four times over.
Cuttlefish — by far the coolest of the cephalopods — are brilliant at camouflage, to the point where they'll actually use their hands and body orientation to mimic objects around them. For the first time, we know that they are relying on visual cues to do so.
This is an illustration of a giant cuttlefish battling brave sailors, depicted in a popular science book from 1872, called The Ocean World, by Louis Figuier. And that's not the least of the weirdness that lurks in Figuier's book.
