Joel Sartore's life project was created in collaboration with National Geographic: the Photo Ark. Joel Sartore traveled the globe, visiting zoos and wildlife reserves to create studio portraits of 12,000 species, some of which are endangered. In his new photo book, he presents his works organized by pattern, shape, and personality, often on a double page for surprising comparisons of various paired animals. New exciting selections of images from Sartore's visual ark, skillfully staged.
