According to the Source Monitoring Framework, the origin of a memory is remembered 11 through the retrieval of specific features (e.g. perceptive, sensitive, affective signals). In two 12 source discrimination tasks, we studied the ability of cuttlefish to remember the modality in 13 which an item had been presented several hours ago. In Experiment 1, cuttlefish were able to 14 retrieve the modality of presentation of a crab (visual vs olfactory) sensed before 1h and 3hrs 15 delays. In Experiment 2, cuttlefish were trained to retrieve the modality of the presentation of 16 fish, shrimp, and crabs. After training, cuttlefish performed the task with another item never 17 encountered before (e.g. mussel). The cuttlefish successfully passed transfer tests with and 18 without a delay of 3hrs. This study is the first to show the ability to discriminate between two 19 sensory modalities (i.e. see vs smell) in an animal. Taken together, these results suggest that 20 cuttlefish can retrieve perceptual features of a previous event, namely whether they had seen 21 or smelled an item.
