An elk rescues a drowning marmot at Pocatello Zoo, Idaho. Keepers were worried when they noticed Shooter, a four-year-old elk, turning his nose up at his water. They looked on baffled as the moose tried to dip his hooves in his drinking trough - before trying to dunk his entire head in the water. But they were amazed when they saw 12-foot-tall Shooter lift his head out of the water - clutching a tiny marmot - a large ground squirrel - between his jaws. They looked on as Shooter gently nudged the rodent with his hoof, to make sure it was alive - before calmly watching it run off into the bushes.
