This cute elephant calf was spotted after it got stuck in a pool of water and required a helping trunk from its mum to get out. The young calf looked like it was having an incredible time however, as it frolicked about in the water and could have done with some waterproofs to boot. But mum clearly knew best with her tot, when she wrapped her trunk around the youngsters body and hoisted it out of the pool. The incident which took place on the Chobe River, Botswana, was captured by Neal Cooper, 50, a professional photographer from South Africa. (Photo by Neal Cooper/Caters News)
