My sister just posted this from her recent trip to the Pantanal, I claim no credit of course but it is just a brilliant shot! This is how she described it "Back home this morning from a trip to the Pantanal in Brazil. Main event was to see jaguars in the wild.....and the greatest spectacle was witnessing the very moment that a fully grown, dominant male cat (known locally as Mick!) took down a sizeable caiman. The stalking took nearly 25 minutes...the kill was over in less than 60 seconds."
