Cephalopod Intelligence
Cephalopods (octopuses, cuttlefish, squids) exhibit remarkable cognitive abilities.
They have complex brain structures, with neurons distributed across their bodies (e.g., arms).
Common behaviors indicating intelligence include visual camouflage and problem-solving.
Behavioral Skills and Learning
Cephalopods can learn through trial and error and can adjust their behavior when stimuli change (e.g., reversal learning).
They demonstrate memory and the ability to form associations, such as recognizing which images predict food.
They can also inhibit impulsive behavior, as shown in studies where they choose delayed rewards (e.g., shrimp over crab).
Animal Welfare and Considerations
Given their cognitive abilities, there is growing concern for cephalopods' welfare in captivity.
Some U.S. states and regions have introduced guidelines for the humane treatment of cephalopods, similar to those for vertebrates.
The European Union and other organizations have begun promoting ethical treatment guidelines for cephalopods in research and captivity.
The intelligence of cephalopods challenges how we view moral consideration for invertebrates.
Decisions on moral consideration may involve criteria like brain structure, neuron count, and learning capacity.
