NBC30news.com reports that a 1 year-old octopus in Denmark's Aquarium has learned how to open the lids of tight jars in ten seconds or less. It isn't tool creation -- like the crow that bent a wire into a hook to get food out of a jar in this experiment -- but it still impressive.
A biologist that works with the animal said it has been curious since birth.
He said the lid-removing octopus is probably the most intelligent animal at the aquarium.
