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.

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 [...]

It’s not very often that a movie comes out that features an octopus as one of the main (speaking) characters. (And they only occasionally become the star of a video game.)

Rare Octopuses Get Their Close-Up

There are some 300 known species of octopus. From the huge giant Pacific octopus (Enteroctopus dofleini) to the tiny poisonous blue-ringed octopus (genus Hapalochlaena), from the shallow-water mimic octopus (Thaumoctopus mimicus) to the deep-sea Dumbo octopus (genus Grimpoteuthis). But most of what we know about the animal comes from a few well-studied, (semi) lab-tolerant species. [...]

Soft Octopus Escape—and Paperback Octopus! Release [Video]

octopus book paperback

Octopuses long ago shed their ancestors’ protective shells in favor of a slinkier, floppier, softer existence. They were perhaps never meant to be held down by hard covers. In fact, many scientists credit this unlikely evolution for their wily intelligence. That is why I am extra excited for the publication of Octopus! The Most Mysterious [...]

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.

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.

First Common Octopus Cannibalism Filmed in the Wild [Video]

octopus cannibalism

Perhaps it’s time we stopped feeling quite so bad about eating octopus. Octopuses dine on other octopuses, too. And for the first time, that behavior has been caught on video in the common octopus in the wild—three times. Cannibalistic behavior in the lab setting is well known. This is one of the reasons octopuses can be so [...]
