A wildlife photographer has captured the brutal moment a jaguar pounces and wrestles a caiman to death on the banks of a Brazilian river.

Chris Brunskill witnessed the big cat ambush the giant jacare caiman, a member of the Alligatoridae family, high up on the Three Brothers River in the Pantanal area of the state of Mato Grosso.

In a Facebook post, Mr Brunskill said he had hurried to the area after receiving reports that a jaguar had been seen nearby.
