A HUNGRY jaguar and a large caiman wrestle in a river for 20 minutes before the big cat finally prevails. Shot in October by wildlife guide, Leen Gillis, 33, the dramatic footage shows the ruthless predator pounce on the unsuspecting reptile while a group of tourists watch in amazement. Filmed in Black Little River in Porto Jofre, Northern Pantanal, the video also shows the jaguar struggling to lift its prey on to the riverbank. The adolescent male, who is new to the area, eventually dragged its prey into the nearby forest and stayed there for the next few days feasting.
