A Snake Bigger Than Science ExpectedThe species has been named the northern green anaconda (Eunectes akayima), and the largest specimen collected during the trip measured an incredible 6.3 meters (20.7 feet) in length. The northern green anaconda is genetically distinct from the southern green anaconda (Eunectes murinus), the previously known record-holder in the anaconda family. This new species, Eunectes akayima, appears to continue that pattern—except it may grow even longer than previously recorded individuals. A northern green anaconda. As climate change and deforestation continue to threaten fragile ecosystems, documenting species like Eunectes akayima becomes a race against time.
