NATIONAL Geographic is putting the world's most vulnerable animals on display in a series of powerful and striking portraits.
The publication’s poignant feature, Photo Ark, is vital as one million species are already on their way to extinction, warns a recent government report.
These images are from the October 2019 issue of National Geographic, and the book, The Photo Ark Vanishing: The World’s Most Vulnerable Animals.
The National Geographic Photo Ark is led by photographer Joel Sartore, and aims to save wildlife by supporting on-the-ground conservation efforts.
Sartore has photographed nearly 10,000 animals – making studio portraits of animals in captivity – to "get the public to care about the extinction crisis while there's still time".
This ambitious project also aims to "capture for posterity species that someday might be extinct.
"To reflect the project's life-preserving mission, Sartore named it Photo Ark," says National Geographic.
Asked about one of the most memorable species to have become extinct over more than a decade of work, Sartore told the publication: "I'd say the Rabbs' fringe-limbed tree frog.
"A few years ago, there was one left alive, a male, at the Atlanta Botanical Garden.
"He was a total sweetheart. I photographed him three times before he passed away [in 2016]."
