- 2003-07-01 (UPDATED 2003-07-11) Chilean Blob: Not A Cephalopod
- A 12 meter long blob was found on a beach in Chile. It was suspected of being a giant octopus. Turned out to be decayed whale blubber.
- 2003-04-01 (UPDATED 2003-05-24) Colossal Squid Caught
- Fishermen near Antarctica have caught a rare, virtually intact specimen of Mesonychoteuthis hamiltoni (or "colossal squid") -- a very large, very aggressive squid with scores of razor-sharp hooks on its tentacles. Includes article round-up, photos and email from Steve O'Shea.

- 2023-06-20 Octopuses Shown To Map Their Visual Landscape Much Like Humans Do (Phys.org)
- For the first time, neuroscientists have recorded neural activity from the visual system of an octopus. "We were able to see that each location in the optic lobe responded to one location on the screen in front of the animal. If we moved a spot over, the response moved over in the brain."
- 2023-06-08 Octopuses Tweak The RNA In Their Brains To Adjust To Warmer And Cooler Waters (NPR)
- Researchers report that octopuses are able to edit genetic information to quickly resculpt their brains when confronted with changes in their environment. Original paper: "Temperature-dependent RNA editing in octopus extensively recodes the neural proteome" (Cell).

- Keep an eye on an octopus taking a nap and you might catch their skin flashing between a sallow white tone and a vibrant color. Amazingly, scientists believe this is evidence of dreaming.
- 2023-04-29 There's A Big Difference In How Octopuses And Squid Taste The World Around Them (Science Alert)
- The last common ancestor between squids and octopuses was around 300 million years ago. Since then, they have had fascinating differences in their adaptations. And one of these is how they taste the world around them.
- 2023-04-26 An Octopus's Stripes Can Act As A Unique ID (Ars Technica)
- UC Berkeley researchers found that the striping patterns of the lesser Pacific striped octopus (aka zebra octopus, Octopus chierchiae) are individualized, similar to our fingerprint patterns, making them easier to track and study in the wild than other constanly camouflaging octopuses.
- 2023-04-18 Octopus, Squid & Cuttlefish Arms Evolved To "Taste" Different Compounds (ScienceNews)
- Cephalopods have proteins on suckers along their tentacles that allow them to "taste" by touching objects. But the species have evolved to detect different compounds, and the differing tastes may be tied to the species' hunting styles.
