Giant Anaconda VS Crocodile! Two amazing predators meet in the water. Only one leaves alive. This is the ultimate battle of the amphibious reptilians of the Amazon jungle. The crocodilian, a Caiman, rests on the river bank, awaiting a meal. Unbeknownst to this reptile, a Giant Anaconda - also known as Eunectes murinus - awaits below the surface. This snake is part of the largest anaconda species. The Anaconda wins the battle by surprising the Caiman. The croc lets its guard down for just a moment, and that's all this massive snake needs. It then swallows its victim whole. The jungle is full of surprises.
