A crew of scientists on location with a movie crew within the distant Amazon has uncovered a beforehand undocumented species of large anaconda.
Professor Bryan Fry from The University of Queensland led a crew which captured and studied a number of specimens of the newly named northern inexperienced anaconda (Eunectes akayima), situated within the Bameno area of Baihuaeri Waorani Territory within the Ecuadorian Amazon.
“Our team received a rare invitation from the Waorani people to explore the region and collect samples from a population of anacondas, rumored to be the largest in existence,” Professor Fry stated. “The indigenous hunters took us into the jungle on a 10-day expedition to search for these snakes, which they consider sacred. We paddled canoes down the river system and were lucky enough to find several anacondas lurking in the shallows, lying in wait for prey. The size of these magnificent creatures was incredible – one female anaconda we encountered measured an astounding 6.3 meters (20.7 feet) long. There are anecdotal reports from the Waorani people of other anacondas in the area measuring more than 7.5 meters (24.6 feet) long and weighing around 500 kilograms (1100 lbs).”

Professor Fry stated the northern inexperienced anaconda species diverged from the southern inexperienced anaconda almost 10 million years in the past, and so they differ genetically by 5.5 p.c.
“It’s quite significant – to put it in perspective, humans differ from chimpanzees by only about 2 percent,” he stated. “This discovery is the highlight of my career.”
Collaboration and Conservation Concerns
The new anaconda species was discovered whereas filming with National Geographic for his or her upcoming Disney+ sequence Pole to Pole with Will Smith, on which Professor Fry, a National Geographic Explorer, was the expedition’s scientific chief.
“Our journey into the heart of the Amazon, facilitated by the invitation of Waorani Chief Penti Baihua, was a true cross-cultural endeavor,” he stated. “The importance of our Waorani collaborators is recognized with them being co-authors on the paper.”

The scientists additionally got down to evaluate the genetics of the inexperienced anaconda with specimens collected elsewhere by world-leading anaconda professional Dr Jesus Rivas from New Mexico Highlands University, and use them as an indicator species for ecosystem well being.
Professor Fry stated the Amazon continues to face alarming ecological threats.
“Deforestation of the Amazon basin from agricultural expansion has resulted in an estimated 20-31 percent habitat loss, which may impact up to 40 percent of its forests by 2050,” he stated. “Another increasing problem is habitat degradation from land fragmentation, led by industrialized agriculture and heavy metal pollution associated with spills from oil extraction activities. Forest fires, drought, and climate change are also notable threats. These rare anacondas, and the other species that share this remote ecosystem, face significant challenges.”
Professor Fry stated his subsequent analysis undertaking would deal with heavy steel air pollution within the Amazon.
“It’s not only these gigantic snakes that are facing environmental threats, but almost all living things in the region,” he stated. “The discovery of a new species of anaconda is exciting, but it is critical to highlight the urgent need to further research these threatened species and ecosystems.
Of particular urgency is research into how petrochemicals from oil spills are affecting the fertility and reproductive biology of these rare snakes and other keystone species in the Amazon.”
