Snapshots of an ever-changing world: Photographers capture incredible moments in nature that will shock and delight you
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.
Others provide a snapshot of intimate moments between two cheetahs surveying the savannah for lions and two flies appearing to kiss.
They are among more than 100 pictures commended in the Veolia Environnement Wildlife Photographer of the Year Competition which were shortlisted from more than 48,000 entries from 98 countries.
Jim Brandenburg, chairman of the judging panel, said: 'It amazes me to discover new and startling moments that have never been seen before.
'Secret moments in nature combined with a talented eye have given us rare photographs that we will truly be enjoyed forever and I am honoured to play a role in such an important competition.’
The duel, by Sergey Gorshkov
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.
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.'
Lion in the spotlight by Joel Sartore
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.'
