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 ...

But there’s undeniably something special about cephalopods – the class of ocean-dwelling invertebrates that includes cuttlefish, squid, and octopus. Critics offer many arguments against ...

"We think it's a feature that specifically evolved in soft-bodied cephalopods with suckers to carry out these worm-like movements." The study, "Neuronal segmentation in cephalopod arms," was ...
