Photographer Lev Fedoseyev filmed a reindeer herd stampeding in a massive spiral in northwest Russia The deer run in a ring when threatened, putting does and fawns in the center, to confuse predators This herd, in Murmansk, was spooked by a veterinarian trying to give them their anthrax vaccinations Reindeer can run 50 miles per hour and, in spring, are known to form 'super-herds' of up to 500,000
