Move over, chimpanzees — there's a new brainiac in town, and this one has gills.
A species of aquarium fish has a surprisingly long memory — it can recall the location of a tasty morsel of food up to 12 days after encountering it, according to a new study. The extended memory may give the fish an evolutionary edge when food is scarce, the researchers suggested.
"Fish that remember where food is located have an evolutionary advantage over those that do not," study co-author Trevor Hamilton, a neuroscientist at MacEwan University in Canada, said in a statement. "If they are able to remember that a certain area contains food without the threat of a predator, they will be able to go back to that area."
