This video and still images were featured, in part, in Nat Geo Wild's broadcast of the Feisty Films Ltd. production "Hunt for the Shadow Cat" during 2011's and 2012's Big Cat Week. Timeline: 0:00 surveying riverbank, 1:46 first jump misses, 4:32 third jump lands on caiman and the battle starts, 5:29 close up with caiman in his mouth, 9:25 excellent close up action, 12:36 bite crushing skull from behind.
While on a Terra Incognita Ecotours trip to the Pantanal in Brazil in August 2010 to observe wild Jaguar, we saw the 6 year old Jaguar "Wilson" (named for the W spot pattern on his head) successfully hunt for Caiman. He wrestled the Caiman for 30 minutes and it was not an easy victory.
