What we can learn from George about aging

On a related note, there's a 3-episode series on Hulu about octopuses.
Not the best I've seen, but still worth a watch.
The documentary comments that most octopuses live only about 8 years. Once they're born, they have no interactions with their parents, so they learn everything on their own. They showed an octopus using a clam shell as a shield - tools.
