Octopus unscrewing jar - GIF

[mklotz]

An octopus at one of the local aquariums accidentally killed itself. During the night it unscrewed the drain plug from the bottom of its tank and all the water drained out. Later, in an interview, its keeper said it was very inquisitive and bored easily. They enriched its environment by giving it screw-top jars containing bits of its favorite foods so it learned all about threaded fasteners.
