You thought your dog could do cool tricks? Cat? Horse? How about octopus? It's not super scientific, but watching an octopus unscrew a jar from the inside has got it all over a horse that counts or a dog jumping through a hoop. Watch the flexibility and maneuverability of this animal. If you look carefully, you can even see the beak at times.
The part that particularly awed and scared me was the animal's seemingly haughty attitude when the feat was accomplished. Mother Nature's pets are an amazing bunch. Go science!
