This is the moment two jaguars face off in a vicious fight over territory.
One remarkable shot shows the long fangs of the jaguar, trying to warn off the intruder with a thundering roar as the pair clashed while hunting by a river in Brazil.
Photographer Reynaldo Leite Martins Junior caught the moment two male jaguars fought on a riverbank in Brazil
At first the animals were wary as they circled each other
Then one of the beasts bared his fangs as he let out a terrifying roar
And leapt dramatically into the air in a bid to injure its opponent during the standoff
Dentist and wildlife photographer, Reynaldo Leite Martins Junior, 53, from Mato Grosso, Brazil, took the photographs from a boat as he tracked one of the jaguars during its hunt.
The pair fought ferociously for supremacy on the river bank each trying to land a vicious definitive blow
But said Mr Martins the encounter only lasted five minutes before the naturally solitary creatures went their separate ways
He added: ‘Witnessing the encounter on a beach, in plain view, was a magical moment that released a significant amount of adrenaline and endorphins into my body.
And the losing beast slunk away to link his wounds
