See What We Can #SaveTogether

Species are disappearing at an alarming rate, but together we can help.

The National Geographic Photo Ark, led by photographer Joel Sartore, is a multiyear effort to document every species living in zoos and wildlife sanctuaries, inspire action through education, and help save wildlife by supporting on-the-ground conservation efforts. And you can help by spreading the word! Learn how you can sound the alarm about species at risk by participating in our #SaveTogether campaign.

Building the Ark


Species to Date



In his quest to document our world’s astonishing diversity, Joel has taken portraits of 7,793 species — and counting! He’s over half way to his goal of documenting all of the approximately 12,000 species living in the world’s zoos and wildlife sanctuaries.

“I want people to care, to fall in love, and to take action.”

Photo Ark founder and National Geographic photographer Joel Sartore has visited 40 countries in his quest to create this photo archive of global biodiversity. To date, he has completed intimate portraits of more than 7,000 species.

No matter its size, each animal is treated with the same amount of affection and respect. The results are portraits that are not just stunningly beautiful, but also intimate and moving.
