In 2024, researchers revealed the discovery of a new species of giant anaconda in South America. A National Geographic camera team was present for the 2022 expedition that recorded the snake—and actor Will Smith was there as well, since they were filming NatGeo’s new documentary series, Pole to Pole with Will Smith. The three-minute clip above lets everyone share Smith’s Amazon experience.
Accompanied by venom expert Bryan Fry, we follow Smith by boat with a group of indigenous Waorani guides, combing riverbanks for anacondas. They locate one: a female green anaconda roughly 16 to 17 feet long, “pure muscle.” The Waorani secure the enormous snake—anacondas aren’t venomous but they can bite—so Fry (with Smith’s understandably hesitant help) can take a scale sample for further study. Fry says the sample will help him assess pollutant buildup in the water.
Those and other collected samples allowed scientists to perform genetic analyses that led to naming a new species: the northern green anaconda (Eunectes akayama, which roughly means “the great snake”). It is genetically distinct from the southern green anaconda (Eunectes murinus); the two species likely split about 10 million years ago. The northern green anaconda’s range includes Venezuela, Colombia, Suriname, French Guiana, and northern Brazil.

During his Amazon visit, the arachnophobic actor also came face to face with a giant tarantula while scientists drew its venom. His travels later took him to the South Pole, where he crossed frozen ice fields; to the Himalayas, where he visited a remote village in Bhutan; to Pacific islands to record an endangered native language; to the Kalahari desert, where he joined San hunter-gatherers on a hunt; and to the North Pole, where he took part in an expedition that dived beneath the ice to collect scientific samples.
Pole to Pole with Will Smith premieres on January 13, 2026, and will stream on Disney+ the following day.
