cephalopod intelligence

Cephalopod intelligence refers to the advanced cognitive abilities of animals like octopuses, squids, and cuttlefish. They demonstrate problem-solving skills, learning, and memory, often using their environment creatively, such as opening jars or mimicking predators. Their complex nervous systems—especially their large brains relative to body size and decentralized nerve centers in their arms—allow them to adapt quickly, exhibit curiosity, and communicate through color changes and body language. This sophisticated behavior makes cephalopods some of the most intelligent invertebrates, showing a level of neural complexity comparable in many ways to vertebrates.
