Capturing the hidden, unfiltered world of the animal kingdom on camera isn't easy. But the winning images from the London Natural History Museum's annual Wildlife Photographer of the Year competition give rare glimpses of animals' resilience.
This year, the photographers behind these pictures climbed coastal cliffs in Norway, trekked through the jungles of Costa Rica, and dove deep into the waters of Indonesia to observe animals' struggles to survive and get a decent meal.
Photographers from 100 countries submitted 48,000 entries for the contest, including photos of an interlocked ant army, a stand-off between a surly fox and a shocked marmot, and a puma ambushing a guanaco.
