Octopuses, squid, and cuttlefish are remarkable creatures, famed for their intelligence. They are invertebrates—animals without a backbone—and are much more distant from us in evolutionary terms than our fellow mammals, far more distant even than birds, reptiles, and fishes. The last common ancestor of humans and octopuses lived over 560 million years ago. These animals have evolved intelligence by a different path, and their ways of perceiving and interacting with the world are very different from our own.
This resource aims to take you inside the minds of octopuses, squid, cuttlefish, and their lesser-known relatives, the nautiluses, using the latest scientific evidence to present an accurate, up-to-date picture of what we know about their capabilities.
