In a remarkable discovery, scientists have identified a new species of giant anaconda in the Ecuadorian Amazon. This revelation came to light during a snake genetics study conducted in 2022, with astonishing footage recently released in a nature series featuring actor Will Smith.
Discovery of the Northern Green Anaconda
The newly identified species, termed Eunectes akayima, is a northern green anaconda. It was observed in the Baihuaeri Waorani Territory, an area teeming with rich biodiversity. The team, led by venom expert Bryan Fry, utilized the expertise of Indigenous Waorani guides to locate and capture this impressive creature.
Footage of the Encounter
The footage, part of the upcoming docuseries “Pole to Pole with Will Smith,” captures the dramatic moment when a giant female anaconda, measuring approximately 16 to 17 feet (4.9 to 5.2 meters) long, was restrained for scale sampling. The presence of the guides was crucial, as green anacondas, while not venomous, can be dangerous due to their size and strength.
Significance of the Discovery
This finding is significant as it highlights the genetic differences between the northern green anaconda (Eunectes akayima) and the already identified southern green anaconda (Eunectes murinus). Genetic studies reveal that these two species diverged around 10 million years ago, accumulating notable differences in their DNA. Specifically, they differ by about 5.5% of their total genetic makeup.
Ecological Implications
The northern green anaconda inhabits the northern Amazon basin, extending across various countries, including Ecuador, Colombia, and Venezuela. In contrast, the southern green anaconda is found in the southern basin, primarily across Brazil and Bolivia.
- Habitat: Northern green anacondas live in wetlands and river systems.
- Diet: Females typically consume lower trophic level prey like deer, while males hunt higher predators such as fish and caimans.
The distinct feeding patterns of male and female northern green anacondas provide valuable insights into the health of their ecosystem. Bryan Fry noted that the males, which often consume more toxic prey, demonstrate higher concentrations of heavy metals—a warning regarding environmental pollution.
Future Research and Conservation
Fry is collaborating on a wild food guide tailored for the Waorani community, aiming to help mitigate health risks associated with consuming contaminated wildlife. This initiative is crucial for protecting both local ecosystems and the well-being of Indigenous populations.
The revelations of the new northern green anaconda continue to underscore the need for ongoing research into these fascinating creatures. As Fry remarked, despite their fame, anacondas remain poorly understood, hinting there may still be more undiscovered species within this iconic group.
Viewers can learn more about this discovery when “Pole to Pole with Will Smith” premieres on January 13 on National Geographic, followed by releases on Disney+ and Hulu on January 14.
