A photographer could bear-ly believe his eyes when a bear started waving at him. The friendly animal wandered to the front of his enclosure before sitting back in full view of zoo guests. He then lifts his powerful paw and excitedly waves in an almost human-like way at his new audience. The hilarious encounter was captured by keen photographer Andrey Slepnev, 31, while on a trip to Madrid Zoo, Spain on March 24, 2016. (Photo by Andrey Slepnev/Caters News)

This is the incredible moment two bear cubs held hands in hope for some dinner as they watched their mother hunt for dinner in a stream. Lewis Kemper, 62, was leading a photography tour in Lake Clark National Park in Alaska when the group spotted the animals and couldn't resist snapping a few pictures of them. The pictures show the two cubs stood side-by-side as the smaller one paws at the bigger sibling's back while they stare intently in the direction of their mum. Then one incredible captures the moment the bears appear to hold hands as their mother hunts for salmon around the lake. (Photo by Lewis Kemper/Mercury Press)
