Meet the 33-foot-long Anaconda and Learn Some Facts About the World’s Largest Breed of Snakes (4 of 4)

Anacondas only need to eat once every few weeks, but when they do develop an appetite, no animal great or small is safe. Sure, they’ll munch on fish and snack on birds, but thanks to their specialized jaw structure that permits them to stretch their mouths widely, they won’t hesitate to eat a delicious jaguar if the opportunity presents itself.

Like most snakes, anacondas don’t have the greatest of eyesight and no amount of LASIK surgery is going to correct that. But thanks to their pit organs, a unique heat-sensing biological structure, they are able to hunt for prey even in chilly, murky waters.
