Watch the video. It’s a perfect line drawing the an elephant. Amazing.
The implications on elephant intelligence are profound. I don’t know of another animal who could do as well. I was impressed by the obvious thought process the animal went through before each stroke. Has anyone given a dolphin a paint brush?
You will notice the trainer ducks out of the way after handing the brush to the animal. On the side you can’t see, the well trained beast is being given trunk movement cues by the trainer. Still the precise control is amazing.
