evidence: A team from the University of Queensland traveled to the Ecuadorian Amazon to search for the previously undocumented northern green anaconda (Eunectes akayima), following an invitation from the Waorani people to observe anacondas "rumoured to be the largest in existence," according to the scientists. [...] Anacondas are giant, non-venomous constricting snakes found in or near water in warm parts of South America. [...] Green anacondas are the world’s heaviest snakes, according to the UK’s Natural History Museum, which noted that the heaviest individual ever recorded weighed 227 kilograms (500 pounds). It measured 8.43 meters long (27.7 feet) and 1.11 meters (3.6 feet) wide.
