Alongside the overall winning images, category winners were awarded for a range of subjects, such as animal portraits, animals in their environment, behaviour of mammals, amphibians and reptiles, birds, and invertebrates, underwater and urban wildlife.
There were also winners in three age categories for the young wildlife photographer competition.
The competition's Young Wildlife Photographer of the Year 2025 was won by Italian Andrea Dominizi, who secured the top award for his "harrowing" shot of habitat loss in the Lepini Mountains of central Italy.
For the second year, the competition included an "impact award" to recognise a conservation success or story of hope or positive change. This year it was won by Brazilian Fernando Faciole for his image spotlighting an orphaned giant anteater pup following its human caregiver, after an evening feed at a rehabilitation centre. Its mother had been killed by a vehicle.
The 10 years and under was won by Jamie Smart (UK). The Weavers Lair by Jamie Smart spotted an orb weaver spider inside its silken retreat on a cold September morning.
The Wildlife Photographer of the Year exhibition at the Natural History Museum, London, will open on October 17 and run until July 2026, and will also go on a UK and international tour.
