Studies have found that, unlike humans, cuttlefish can still retain a keen memory of specific events when they are old

Researchers found that cuttlefish can remember the time, place, and time of specific events until the last few days of their lives

Researchers from the University of Cambridge in the United Kingdom and the Woods Hole Marine Biology Laboratory (MBL) in Massachusetts said: They have conducted a memory test on 24 common cuttlefish with the University of Caen in France

"Cuttlefish can remember what they ate, where and when, and use this to guide their future eating decisions

As humans age, they gradually lose the ability to remember experiences at specific times and places—for example, what dinner we had last Tuesday

Cuttlefish do not have a hippocampus, and their brain structure is very different from ours

In order to carry out the experiment, first train the cuttlefish to approach a specific location marked with a black and white flag in the aquarium

Then, the squid recalled which foods were available, where and when they were tested

"In the memory task, old cuttlefish are as good as young cuttlefish-in fact, many older cuttlefish perform better in the test phase

Hanlon added: “We have done extensive research on cuttlefish in the wild and in the laboratory for decades, but these complex behaviors are even a surprise for us

Cuttlefish have a short lifespan, most of which can only live to about two years old, which makes them a good target for testing whether memory will decline with age
