A Greyhound dog drinks water after a race in Santiago city, in this file picture taken March 1, 2014. Popular web videos showing that “cats rule and dogs drool” have new scientific evidence to support that felinophilic sentiment, at least when it comes to drinking. While cats expertly manipulate water to quench thirst neatly, dogs smash, slosh, spill, and splash their way, according to research unveiled on November 24, 2014. (Photo by Ivan Alvarado/Reuters)

A mother baboon lifts its baby into the air, on March 24, 2013, in Kruger National Park, South Africa. It's a scene we've witnessed before – doting parents playing aeroplane with their young child. But astonished tourists watched as a loving baboon played the popular human game with its young. The touching moment was spotted in the Kruger National Park, South Africa, by Mariana de Klerk, 54, in March 2013. The pictures, which have not been seen before, clearly show the delight on the newborn's face as its mother lovingly lifts it up to the sky. (Photo by Mariana de Klerk/Barcroft Media)

While other studies have made similar pronouncements, this report gives the most comprehensive projections to what is likely to happen to America's birds. (Photo by Wilfredo Lee/AP Photo)

It looks like an underwater tornado – but a diver was actually stuck in the middle of a huge school of fish. The fish swarmed around Mika Woyda in their thousands as she swam off the coast of Cabo Pulmo, Mexico. Her husband Caine Delacy snapped the breath-taking images of Mika in scenes he revealed he had never witnessed in 20 years of diving. Before entering the water the couple, who live in Boulder, Colorado, USA, had some shots in mind but never imagined what they would capture. (Photo by Caters News)
