These incredible photographs show nature's beauty and brutality in equal measure.
Some will delight, others will shock, but all capture the stunning variety that exists in the animal kingdom and the interactions that go on there.
In one, an eagle lunges at a hungry fox, while another shows a terrified baboon struggling to free itself from its shackles among a group of children.

Some also cast a light on our ever-changing relationship with the natural world.
One of those was taken by African photographer Jabruson who exposes the shocking cruelty that some wildlife face in our hands as a terrified baboon vies for freedom from a group of children.
In the spotlight: A lion poses up a tree in Queen Elizabeth National Park, Uganda, in one of the more artistic offerings in the shortlisted images for the competition
Jabruson explains: 'This young animal was caught during a troop crop raiding on the highway in north-eastern Mozambique. I realised that if I could take an image I could help highlight the situation.'
From the opposite corner of the globe, a cheeky fox learns his lesson as an eagle attacks it for attempting to steal its prey, while Klaus Tamm's Sizing up appears to depict the intimate caress of two flies.

The two male neriid long-legged flies were, in fact, engaged in a combat dance which finished with them stretching up to their full height, before flying away and mating with nearby females.
Tamm said: 'I was so impressed by the harmony in the combat dance that I ended up photographing them for several hours.'
