Video by @bertiegregory. What do you do if you're a capybara and a jaguar is coming for you? JUUUUUUUMP! Caiman aren't the jaguar's only prey in the Pantanal, Brazil. The world's largest rodent, the capybara, is also near the top of the menu. But looking like a giant ginea pig, you might think they're sitting ducks. Far from it. Capybara are on constant alert and are never far from their emergency exit- the river. Whenever they sense danger, they let out a loud bark (to alert their family group) before launching in! Stay tuned for our new jaguar show for @natgeowild premiering later this year. Shot for @stevewinterphoto and @natgeo. Follow @bertiegregory for more wildlife adventures.
