How can the soft bodies of coleoid cephalopods so aptly hide in their environment? Why must they? What cells and specialized organs make such crypsis possible for one of the older evolutionary ...

Findings on cephalopod nerve cords highlight segmentation's role in sucker movement control, advancing knowledge of neural ...

The researchers believe the “suckeroptopy,” as they called the map, facilitates this complex sensory-motor ability. To see if ...

Just how smart are cephalopods, really ... In other species of octopus, the general structure is similar, but complexity varies. Wrinkles and folds in the brain increase its surface area and ...

Marine biologist Roger Hanlon explains the distributed structure of cephalopod brains and how they use that neural power. Intelligence is fiendishly hard to define and measure, even in humans.

Because brain structure is not a foolproof measure of intelligence, behavioral tests may provide better evidence. One of the highly complex behaviors that many cephalopods show is visual camouflage.

Drawing on over 300 scientific studies, we have evaluated the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid ...

Because brain structure is not a foolproof measure of intelligence, behavioral tests may provide better evidence. One of the highly complex behaviors that many cephalopods show is visual camouflage.

To see if this kind of structure is common to other soft-bodied cephalopods, Olson also studied longfin inshore squid (Doryteuthis pealeii), which are common in the Atlantic Ocean. These squid ...
