Cuttlefish Have Complex Cognitive Abilities


A new study recently revealed that cuttlefish possess complex cognitive abilities and decision-making skills, which are learnt from their past experiences. In an experiment conducted by researchers at the University of Cambridge, UK, when cuttlefish were subjected to a fixed feeding schedule, they ate fewer crabs in the day as they were fed their favourite food–shrimp–every evening. However, when they were given shrimp on a random basis or at uncertain times, the cuttlefish ate more crabs during the day. This behaviour is selective and opportunistic, proving that cuttlefish were making a decision based on programming. Cuttlefish are born with a large nervous system, which enables them to learn from a young age. The changing behaviour of the cuttlefish with changing conditions showed their ability to remember things from the past and change their behaviour based on future predictions.
