They filmed British stoats (known as the short-tailed weasel/ermine in N. America) single-handedly killing and dragging home rabbits that were four times their weight and size (stoats are smaller than squirrels!)

You learn something new every day on FR. I've read English literature which referred to stoats in an offhand manner (T.H. White, among others, I think) and I always thought they were referring to some tamer creature. Geez, now I gotta re-arrange my ganglia.

For their size, they are about as vicious as you can get. Beautiful creatures though. Recent research suggests that they're a key factor in the boom-bust cycles of lemmings in northern latitudes.

Picture of a wolverine ( hint: look at the feet ). These suckers weigh about 40-45 pounds. Imagine a 200 pounder.
