How about a Snow Leopard? Now that would be cool.... Just kidding..
If I could only choose one DG animal? Hmmm... I would have to go with the Great White Bear as well. Polar Bears have to be one of the toughest animals on Earth. They live out on the "sea-ice", can swim 20+ miles in 33 degree water, and when they get out of the water, the ambient air temp is -40. Just another day....They're one tough animal!!! And from what I'm told it's quite the hunting experience as well, hunt's are all done by dogsled, and there's no such thing as going back to the Lodge for the night. Someday....
