In an unprecedented effort, 15 aquariums from around the world are teaming up to raise endangered baby zebra sharks and reintroduce them into the wild, where populations have nearly gone extinct. National Geographic photographers Jennifer Hayes and her husband David Doubilet documented this process of "rewilding" from the waters of Raja Ampat, an archipelago in the West Papua province of Indonesia, where these slow-moving sharks have nearly disappeared due to fishing. ReShark aims to release 500 zebra sharks over the next 10 years
