Cephalopods such as octopus and squid evolutionarily diverged from mollusks like slugs and snails. These animals have elaborate compact nervous systems located within specialized arm appendages, which ...

Research has traced the evolutionary adaptations of octopus and squid sensing capabilities. The researchers describe for the first time the structure of an octopus chemotactile receptor, which octopus ...

In a new study, researchers used a new live-imaging technique to watch neurons being created in squid embryos almost in real-time. They were then able to track those cells through the development of ...

Along their eight arms, octopuses have highly sensitive suckers that allow methodical explorations of the seafloor as they search for nourishment in a “taste by touch” approach. Squids, on the other ...

Cephalopods — which includes octopus, squid, and their cuttlefish cousins — are capable of some truly charismatic behaviors. They can quickly process information to transform shape, color, and even ...
