While modern octopuses have DNA that consistently gets reshuffled, resulting in some chromosomal mixing, the researchers found that the vampire squid's genome kept much of its ancestral, squid-like ...

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 ...

Scientists have sequenced the genome of the "vampire squid from hell," revealing it bridges the evolutionary gap between ...

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

From the first sighting of a colossal squid in the wild to a seriously goofy octopus, 2025 delivered some astounding photos ...

Coleoid cephalopods have the most elaborate camouflage system in the animal kingdom. This enables them to hide from or deceive both predators and prey. Most studies have focused on benthic species 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 ...

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 ...
