Octopus Intelligence

With its eight powerful arms, an octopus can swim backward or pull itself over rocks on the ocean floor. An octopus is very strong, but is it intelligent? People at the Hellabrunn Zoo, in Germany, might have an opinion about this.
Glass jars don't exist in the ocean, the natural environment of an octopus, so you might not expect an octopus to know how to open one. However, at the Hellabrunn Zoo, an octopus named Frieda had the motivation to learn how to open a jar. The motivation was food. Frieda watched her human keepers as they opened glass jars with food inside. From watching them, she learned how to twist off the lid and reach inside for the food.
Interestingly, she will not open just any jar. She doesn't open jars that contain fish. According to a representative of the zoo, "She will open only jars containing her favorite foods, such as shrimp, clams, and crabs."
