Octopuses, squid and cuttlefish may have evolved large brains because of the challenges posed by their environments rather ...

(Eric VOLTO/500px/Getty Images) Biologists have long believed that having a large brain, relative to your body, might go hand ...

Because we needed to keep a running tally of friends and foes to navigate thorny hierarchies and shifting alliances, we had to have brains that were up to the task (which is why this theory is also ...

The spatial organization of chromatophore-muscle innervation by motoneurons enables the generation of chromatophore-shaped noise, virtual or composite chromatophores, and shape elements such as lines ...

Cephalopods, including octopuses, cuttlefish and squid, possess some of the most elaborate nervous systems and behavioural repertoires among invertebrates. Their large central brain, organised into ...

Computational fluid dynamics can be used to study how extinct animals used to swim. Scientists studied 65 million-year-old cephalopod fossils to gain deeper understanding of modern-day cephalopod ...

We wish could ask cephalopod scientists questions for eight days straight, but the next best thing is an hour-long reddit AMA. From SailboatAB: When I read about cephalopod intelligence, it’s always ...

Researchers have sequenced and annotated the first cephalopod genome, the California two-spot octopus. They found widespread rearrangements of genes and a dramatic expansion of a family of genes ...

A cute observation in the cephalopods' behavior indicates they also react to sound waves, a notion that will soon be tested with a machine learning approach. Reading time 3 minutes Researchers just ...
