Are humans on an anaconda's menu? It may surprise you to learn that there are no documented records of this snake eating a human. This doesn't mean that it has never happened. Indeed, two of my research assistants have been attacked in the field.

Five weeks ago, scientists discovered the largest snake in the world. Now it has been found dead in the Brazilian rainforest. In February, researchers were with a team filming a National Geographic series — Pole to Pole with Will Smith — when they made an incredible discovery.

Scientists have discovered the world's biggest snake in the heart of the Amazon rainforest. A giant anaconda, which was previously undocumented, was recently found by TV wildlife presenter, Professor Freek Vonk during a National Geographic expedition.

The heaviest anaconda ever recorded was 227 kilograms. This massive snake was 8.43 metres long, with a girth of 1.11 metres. While the reticulated python is longer, it's also slender. Anacondas are bulky.
