That is truly spectacular.

Reminds me of the story I heard about dolphins being smart: There were dolphins somewhere, like a seaworld, or in another marine exhibit. They were trained to bring up litter that made its way into their holding tank, and for this they would be rewarded with a treat. Turns out the dolphins had the trainers one-upped because when they found a piece of litter, like paper, they would wedge it under a rock and tear a small piece off and take it to the trainer whenever they wanted a treat. Who's training who these days? LOL
