An octopus in a German zoo has learned to open jars of shrimps by copying staff – and is now showing off her skills to visitors.

Five-month-old Frida opens the jars by pressing her body on the lid and grasping the sides with her eight tentacles.

She unscrews the lid by repeatedly twisting her body.

“Depending on how tight the lid is, it takes her anything from 10 seconds to an hour to get it off,” said Frank Mueller, head of the aquarium at the Hellabrunn Zoo in Munich.

She opens the jars before the public at feeding time twice a week.
