To perform these processes and others, like crawling or exploring, octopuses rely on their complex nervous system, one that ...

Known as the soft-bodied or coleoid cephalopods, they have the largest nervous system of any invertebrate, complex behaviors such as instantaneous camouflage, arms studded with dexterous suckers ...

“We now have a model cephalopod where we can interrogate biological function at much higher resolution than before.” The nervous system and behavior of coleoid cephalopods (squid, octopus and ...

The study, "Neuronal segmentation in cephalopod arms," was published January 15, 2025, in Nature Communications. Each octopus arm has a massive nervous system, with more neurons combined across ...

"We think it's a feature that specifically evolved in soft-bodied cephalopods with suckers to carry out these worm-like movements." The octopus nervous system is among the most unusual on Earth.

Scientists at the Marine Biological Laboratory created an albino strain of bobtail squid (on left) that allows for clear optical viewing of the nervous system in a living cephalopod for research.

However, although previous research has described the general anatomy and neural richness of cephalopod arms, the detailed ...

“If you're going to have a nervous system that's controlling such dynamic movement, that's a good way to set it up,” said Clifton Ragsdale, Professor of Neurobiology at UChicago and senior author of ...

In most of a cephalopod’s body, RNA editing doesn’t often affect the makeup of proteins. But in the nervous system, it’s a different story. In longfin squids’ nervous systems, 70 percent ...
