Who is the biggest predator in South America? We find out in the video above. In this archived footage, we can see a panther grappling with an anaconda, but the strongest animal is not always the bigger of the two. Weighing in at 136 kilograms, the anaconda is a big guy compared to the 91 kilogram panther. But the fight doesn’t take place in its preferred environment. Anacondas almost always live near on or in the water. They are fairly slow and limp when moving on land due to their size, but they can still be really fast in water. As the footage proceeds to show, the cleverly tries to draw its opponent into a pond. Once in the murky water, the feline predator finds it difficult to grab the anaconda as it makes its way in and out of the water. The anaconda carefully manages to curl around the feline and it seems it isn't be long before she suffocates. Nevertheless, drags the anaconda onto dry land once again before the giant, exhausted snake ends up admitting defeat.
