Long Pointy Snouts Protect Snow-Diving Foxes From Injury

They rely on their keen hearing to pinpoint the precise location of a small prey animal, usually a mouse (or a lemming, in the case of an Artic fox) as it moves under the snow, then they jump high into the air and dive nose-first into the snow at speeds of up to 4 metres per second to catch their dinner by surprise.
