The baby cephalopod looks and behaves like an adult from the moment it emerges from the egg.

The cephalopod’s unique ability to disguise itself relies on a single motor nerve exclusively dedicated to skin tension and papillary control.

As it matures, this chromatophore-clad pyjama squid (Sepioloidea lineolata) hatchling will learn to use the color-changing cells that adorn its body to alter its appearance.

Octopus, cuttlefish, and squid extensively edit messenger RNAs in an evolutionarily conserved process. 

What researchers are learning as they sequence, map, and decode species’ genomes

Squid, cuttlefish, and octopuses possess vision machinery in their skin.

Polymer changes color and texture in response to remote signals. 

Deep-sea octopus has the longest-known brooding period known for any animal species.

Researchers uncover a self-recognition mechanism that prevents octopus limbs from becoming entangled, despite their powerful suction.
