Octopus Play and Squid Eyeballs—and What They Can Teach Us about Brains

For cannibals, octopuses seem to be surprisingly fun loving. Some have been observed using their funnels to repeatedly blow objects around in their tanks. Others, such as one common octopus named Dorian, have spent a countless minutes passing Lego blocks around among their many arms or towing them back and forth across the surface of [...]

Mistaken Octopus Sex Identity Leads to Multi-Armed Wrestling Match [Video]

The octopus, by in large, practices very safe sex. You would, too, if you and the object of your affection were both cannibals. But the algae octopus (Abdopus aculeatus) has developed a relatively sophisticated mating system that involves far more close contact than many other octopus species. In populations of these cephalopods, males and females [...]

New Octopus Disguise Material for the Human World [Video]

It’s no doubt that, with a repertoire of everything from colorful coral to a poisonous sea snake, the octopus could win any costume contest handily. But while most of us are picking our way through fake fangs and unnecessarily revealing outfits, one team of researchers is working to bring the octopus’s camouflaging skills to the [...]

Is Smell the Key to an Octopus’s Heart?

We know that octopuses have awesome visual systems and super-sensitive suckers. We have even learned that they can hear. But little scientific attention has been paid to their sense of smell. And new research suggests that the octopus’s olfactory system could play a strong role in the octopus’s life cycle—especially when it comes to mating. [...]

It’s Octopus Awareness Day, and although we at Octopus Chronicles treat every day as if it were a celebratory day for the cephalopod, today it gets extra special treatment. So to ring in the best day of the year, here are eight of the most famous—and infamous—octopuses—real and perhaps occasionally mythical: 8. Billye: This hungry [...]

Glowing Octopus Bacteria Light Up Living Lamp [Video]

Octopuses might be charismatic, but not many can literally light up a room. One enterprising designer, however, has figured out how to repurpose bacteria from rare glowing deep-sea octopuses for terrestrial illumination. In the form of a stylish lamp—that requires no electricity. [See video below.] Inspired by glowing, bioluminescent waves, graduate student Teresa van Dongen, [...]

Wireless Robot Octopus Swims with the Fishes [Video]

Robot octopuses can already walk, jet along and even grasp tools. But new advances have these machines swimming faster than ever. And thanks to the addition of soft, fleshy webs, they’re starting to look—and move—much more like the real thing, too. In fact, the latest octopus robot has already been for a successful swim—alongside real [...]

8 Great Octopus Videos! [Video]

It’s Octopus Chronicles‘ 88th post! To celebrate, I’ve gone on an all-arms hunt through the deep crevasses of the internet to find eight of my favorite octopus videos. Some are old classics (such as Roger Hanlon‘s amazing, reverse-vanishing octopus) and others are new and stunning—and one even features an octopus walking (slithering?) on land. Really, [...]

Will Climate Change Bring an Invasion of the Octopuses—Or Halt It?

Climate change is bad news for many species. Environments are changing more rapidly than plants and animals can adapt to—or move out of—them. Octopuses, however, reproduce so quickly (and multitudinously) and have such short generation times, they are generally well primed to adapt and move.  The common Sydney octopus (Octopus tetricus), for one, is expanding [...]

Common Octopus Proves Uncommonly Difficult to Define

The seemingly ubiquitous common octopus (Octopus vulgaris) is our platonic octopus ideal. Even if Plato didn’t write about it, Aristotle did. And since then, it has been the most widely studied (and consumed) species. But contemporary science is complicating things, a new paper, published this month in the journal Frontiers in Ecology and Evolution, details. The [...]

In NC, the Science Show Doesn’t Go On

You remember sea-level rise, and North Carolina. I won’t bore you — the legislature was against even measuring it, and a lot of people noticed. In the end, the legislature passed a law just making it illegal for the state to base its plans on modern climate science. And we here in North Carolina were [...]

Plenty of Fish in the Sea?

In 2010, people across the globe munched their way through 128 million tons of seafood. That’s according to the latest data coming out of the UN Food and Agriculture Organization (FAO). This hefty supply of fish equals around 41 pounds per person each year, and is taking its toll on the health of the oceans [...]

Et Tu, Virginia? Again with the Sea Level Rise

At the risk of becoming Plugged-In’s “Those crazies are at it again” correspondent, I would like to bring your attention to two noteworthy developments regarding sea level and politics, and then I hope to wash my hands of the topic — with higher sea levels making hand-washing especially convenient, of course. The first concerns the [...]

From: Louis Figuier, The Ocean World: Being a description of the sea and some of its inhabitants, 1872. Perusing the stacks in the University of Chicago’s Crerar Library one day, I found this gem of a book – a richly illustrated account of sea creatures from 1872 by a naturalist named Louis Figuier. In it [...]
