Cuttlefish have such a powerful memory that they can recall what they had for last week's dinner until they die of old age, a new study has revealed. Researchers from the University of Cambridge conducted an experiment on 24 common cuttlefish to test their memory. Researchers suggest this is the first evidence of an animal whose memory of specific events does not deteriorate with age. Half of these were 10-12 months old – not quite adult – and the other half were in old age at 22-24 months, equivalent to humans in their 90s. In the study, cuttlefish were first trained to approach a specific location in their tank marked with a black and white flag.
