This lion upset a pride of lionesses and lost a testicle for his trouble after they pounced on him for trying to take food from their young.
Mandevo the lion tried to swipe a buffalo kill from the new mothers, not realising it was meant for their 11-strong brood of cubs.
Mandevo suffered a nasty bite to his genitals during the fight in Maasai Mara, Kenya, that left vets no choice but to remove one of his testicles.
Photographer Gren Sowerby captured the cat fight on camera, allowing him to raise the alert rangers who moved in to administer veterinary treatment.
Mr Sowerby, from Whitley Bay, Tyne and Wear, regularly visits the area to photograph the animals.
The 71-year-old said: ‘The roar was like an F1 car! He laid down and licked himself.
‘We were surprised but have seen this behaviour before. We saw the damage done to him.’
If Mr Sowerby and his team had not seen what happened, Mandevo may not have received urgent treatment for his injury.
He added: ‘The rangers sent a vet out from the Nairobi Elephant Orphanage.
‘He did surgery on him and he is now recovering in the wild where they will monitor him.’
