BentÅ-lovers celebrate self-packing octopus

Fans of the traditional Japanese boxed lunch have welcomed news of a self-packing octopus. Staff at the New England Aquarium were able to encourage a 7-foot Giant Pacific Octopus to cram itself into a tiny 15" box. Aquarist Bill Murphy said:

I place one or two live crabs inside the box and the octopus has to learn how to open the box to get the food. I start the octopus off with the small box and once he has mastered the lock I switch to another box and once he has mastered each individual box I put a box inside a box to keep him active and challenged.
