8126534625_c2405e8833_q

Halloween is a peculiar holiday, especially for dogs. We two-legged beings all look different, and what’s with the constant doorbell-ringing? Weren’t you just here. Oh, I’m sorry. You’re Batman. He-Man was just here. My bad. I’ll keep barking. Dogs don’t exactly excel at Halloween, and here’s the lowdown on dogs, costumes, tricks, and treats. 1) [...]

Octopuses and squids are damaged by noise pollution

squid hearing damaged by ocean noise pollution

Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving. "We know that noise pollution in the oceans has a significant impact on dolphins and [...]

A tool-wielding octopus? This invertebrate builds armor from coconut halves

octopus tool use coconut

A clever octopus made headlines earlier this year after it swiftly disassembled part of its tank at the Santa Monica Pier Aquarium in California. But out in the open ocean its relative, the veined octopus (Amphioctopus marginatus), has upped the cephalopod intelligence quotient by using coconut shells as tools. The dexterous octopuses were observed stockpiling [...]

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 [...]

Dumbo Octopus Gives Rare View [Video]

New, stunning video from a deep-sea vehicle reveals a rare view of the Dumbo octopus. Don’t let the name fool you—the Dumbo octopus (Grimpoteuthis) is no dummy. And those protrusions on the side of its body are not—like its cartoon namesake flaunts—big ears, but rather fins, which help it swim above the seafloor. This strange and [...]

Octopus-Inspired Camouflage Flashes to Life in Smart Material

Octopuses and their cephalopod cousins are the undisputed masters of disguise. An octopus can change its color, texture and luminosity faster than you can say “camouflage.” So far our lowly human attempts at imitation have been quite crude. But a flashy new smart material might just be our closest step yet. The main tool the [...]

Happy 8/8! Can You Spot These 8 Hiding Octopuses?

octopus

We must wait patiently two more months until the official International Octopus Day. But August 8th (8/8) is reason enough to celebrate these awesome, eight-armed creatures. But octopuses are the shy retiring type. With darn amazing camouflage. Even experienced underwater divers and scientists often have a difficult time spotting them (I sure did when I [...]

Octopus Eggs Need Helpful Bacteria to Stay Healthy, Too

We’re just learning how important certain microbes can be to our own health. They can help us digest foods and protect us from harmful invaders. New research suggests that certain bacteria are also crucial for octopuses—especially when they’re just starting out. The findings were published online in Aquaculture Research earlier this month. A team of [...]

Scrawny Wonderpus Puts Stranglehold on Mightier Mimic Octopus

octopus

Earlier this week, we learned that female octopuses sometimes strangle—and then possibly eat—their male mates. For a cannibalistic animal with long arms, perhaps we—and the male—should have seen that one coming. (Especially since the female apparently had already gotten what she needed out of the rendezvous.) But an additional report finds that octopus strangulation is [...]

Female Octopus Strangles Mate, Then Eats Him

octopus

Octopuses do the darndest things. Like kill their mate during mating—by strangling him with three arms, according to new observations from the wild. Enterprising scientists Christine Huffard and Mike Bartick watched wild octopuses in action. They found that, for males, mating can be a dangerous game. Especially when your lady has long limbs. Some of [...]

DNA Finds New Octopus Species Hiding in Plain Sight

octopus

Describing a new species for science is not quite as easy as it was in the days of 17th- or 18th-century naturalists. But that just means we have to look a little more closely. Such as, into an organism’s DNA. And rather than hunting through the dense jungles for years, scientists can, with a little [...]

How Do Octopuses Navigate?

Getting around is complicated business. Every year, animals traverse miles of sky and sea (and land), chasing warmth or food or mates as the planet rotates and the seasons change. And with such precision! Some animals rely on visual landmarks, others on subtle changes in magnetic fields, and yet others match their internal clocks with [...]

Say you’re visiting Los Angeles and you have a sudden craving for Chinese food. Since you are only visiting, you might not be aware that nothing is open past, like, 10pm (not even coffee houses), but you get in your rental car and go driving around in search of your Chinese feast anyway.

The tragic fate of the Brighton octopus

A nursehound swallowed the Brighton octopus whole.

These are good times to have tentacles. Thanks to the internet, even the most ordinary of octopuses can be catapulted to worldwide fame. Exceptional skills or abilities are not required. A simple coconut hiding act or a short crawl over land are more than enough to break the internet headlines. But as this new generation [...]
