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

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 ...

Learn more about the genetics of the vampire squid — a strange species whose genome suggests that modern octopuses, squids, and cuttlefish evolved from a squid-like ancient ancestor. According to a ...

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 ...

WOODS HOLE, Mass. – Squid, octopus, and cuttlefish – even to scientists who study them – are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous ...
