Why squid and octopuses have such large brains
Cephalopods, which include octopus, squid, and their cousins the cuttlefish, exhibit some genuinely endearing habits. In order to blend in with their surroundings, they may quickly analyze information to change their shape, color, and even texture. They can also use tools to solve issues, communicate, and exhibit signs of spatial learning. They’re so intelligent that they may experience boredom.

ABSTRACT Background Cephalopods play a major role in marine ecosystems, but knowledge of their feeding ecology is limited. In particular, intra- and inter-individual variations in their use of resources has not been adequatly explored, although there is growing evidence that individual organisms can vary considerably in the way they use their habitats and resources.

Research Summary: Chromatophore Activity during Natural Pattern Expression by the Squid Sepioteuthis lessoniana: Contributions of Miniature Oscillation
ABSTRACT Squid can rapidly change the chromatic patterns on their body. The patterns are created by the expansion and retraction of chromatophores. The chromatophore consists of a central pigment-containing cell surrounded by radial muscles that are controlled by motor neurons located in the central nervous system (CNS). In this study we used semi-intact squid (Sepioteuthis … Continue reading
