In 1998, Nicky Clayton from the University of Cambridge published the first of many seminal experiments with western scrub-jays, showing that they can remember where they had stored food and which hoards were freshest. In other words, these bird brains also have episodic-like memories. We say “episodic-like” since we can’t really know if the animals store their what-where-when information into single coherent memories in the way that we do. Still, it’s clear that the components are there.
Since then, the episodic-like memory club has grown to include the great apes, rats, hummingbirds, and pigeons. But these are all mammals and birds. Christelle Jozet-Alves from Normandie University wanted to know if the same skills existed in animals that are very different to these usual suspects. She turned to the common cuttlefish (Sepia officinalis).
Like octopuses and squid, cuttlefish (Sepia officinalis) are cephalopods—a group of animals known for their amazing color-changing skin and sophisticated intelligence. Cuttlefish are separated from birds and mammals by almost a billion years of evolution. But Jozet-Alves, together with Clayton and Marion Bertin, has shown that they too can “keep track of what they have eaten, and where and how long ago they ate”.
I was flipped off by a cuttlefish at the aquarium. Comic and photographic evidence.

The cuttlefish can change its color, pattern, shape, and texture on command to blend into their environs, communicate with other cuttlefish, and to threaten potential predators. They can also produce undulating lights to confuse their prey. These cephalopods are considered among the most intelligent invertebrates.
