Amazon Discovery Reveals Two New Anaconda Species and Pollution's Toll
During a National Geographic shoot in the Amazon with Will Smith, scientists encountered a 7.5-meter green anaconda and revealed that what was once considered a single species is actually two: the Ecuadorian and Brazilian green anacondas. Ecuadorian snakes are longer on average; pronounced male–female size differences influence their prey choices; heavy-metal testing found males carry up to ten times more lead and cadmium due to oil pollution, illustrating how contaminants move up the food chain and threatening biodiversity, especially the Brazilian species with its smaller range.
