Una expedición en el Ecuadorian Amazon has unveiled a surprising discovery: a new species of anaconda, previously unknown to science. The anaconda, which measures 6.3 meters and weighs around 500 kilos, was documented during the filming of a documentary.
Discovery of the Northern Anaconda
The international team participating in the documentary Pole to Pole with Will Smith managed to identify what has been proposed as the Northern Green Anaconda. This specimen was studied in the Bameno region, within the Waorani territory, under the direction of Professor Bryan Fry from the University of Queensland.
The purpose of the expedition was not simply to capture impressive images of a giant snake, but also to conduct a genetic and observational study. The local knowledge of the Waorani was crucial in this process, so much so that they were recognized as co-authors in the scientific study.
The documentary series featuring Will Smith not only showcases extreme landscapes but also provides valuable data on biodiversity. During the recordings in the Amazon, a sample from a female around 5 meters long was taken to analyze the ecosystem.
Genetic analysis revealed two distinct lineages within the genus Eunectes, suggesting an evolutionary separation of nearly 10 million years between the northern and southern green anaconda. Although visually similar, the DNA shows significant differences.
Local reports indicate the existence of anacondas up to 7.5 meters, although the scientific team only confirmed the direct measurement of a 6.3-meter specimen. This underscores the importance of indigenous knowledge for science.
Females of this lineage are notably larger than males, who reach up to 3.5 meters. These data are not only fascinating from a biological standpoint but also reveal critical information about the state of the environment.
Anacondas, situated at the top of the food chain, can indicate the health of the ecosystem. Differences in diet between males and females reflect variations in levels of heavy metals, pointing to pollution issues affecting both fauna and human communities.
The study has sparked a debate about the correct taxonomic classification, with some experts calling for further research. However, the discovery highlights the need for protection and conservation in the Amazon region, which faces threats from human activities.
Despite controversies over its classification, the story of this anaconda highlights the richness of biodiversity and the importance of collaboration with indigenous communities to understand and preserve the unique ecosystems of the Amazon.
