Photographs by Tim Flach; Text by Dr. Jonathan Baillie; Published by Abrams
Photographer Tim Flach is renowned for his photos that show the emotional - or human - side of animals.
Flach's images often capture creatures' moods, expressions, and gestures in ways that make us rethink our relationship with the natural world.
His newest book, "Endangered", includes text by zoologist Jonathan Baillie and tries to make readers consider the impact they have on these animals - and consider what it would mean for them to disappear.
Along with the creatures themselves, Flach photographed the landscapes these animals live in.
He spent days in frozen snow to capture a shot of the rare Siaga antelope. He swam with sharks and hippos, and visited zoos for perspectives of wildlife in settings created by humans.
The ecosystems in which many of these creatures live have already been destroyed to make room for cities and farms. But by eliminating such habitats, we remove the only places some of the most unique creatures on Earth can live.
