There's more to the paper, though only six cuttlefish: >The other part of the experiment was to test how good the six cuttlefish were at learning. They were shown two different visual cues, a grey square and a white one. When they approached one, the other would be removed from the tank; if they made the "correct" choice, they would be rewarded with a snack. >Once they had learnt to associate a square with a reward, the researchers switched the cues, so that the other square now became the reward cue. Interestingly, the cuttlefish that learnt to adapt to this change the quickest were also the cuttlefish that were able to wait longer for the shrimp reward. https://rs.figshare.com/articles/dataset/Data_set_raw_training_trials_for_reversal_learning_task_from_Cuttlefish_exert_self-control_in_a_delay_of_gratification_task/14054186?backTo=/collections/Supplementary_material_from_Cuttlefish_exert_self-control_in_a_delay_of_gratification_task_/5309888 https://rs.figshare.com/articles/dataset/Data_set_raw_traini...
