A five litre water tub turned lemur feeder when primate keepers filled it with treats as an enrichment project in Lemur Wood.
Small pieces of apple and banana are inserted into the tub which is then suspended from a nearby tree.
Trainee Keeper, Stephanie Sawyer, said: “It’s quite funny to see which lemurs can figure out how to get to the treats.
“Some are defeated by it, others work it out easily and a few naughtily wait underneath for the food to come out.”
