Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).[2][3] Published in 1887, the chronophotographic series comprised 781 collotype plates, each containing up to 36 pictures of the different phases of a specific motion of one subject (over 20,000 images in total).[4]

Following motion studies in California and his lectures with the zoopraxiscope, Muybridge was commissioned by the University of Pennsylvania to oversee the photographic aspects of a scientific study of animal movement. The body of work is celebrated for its contribution to both the art of photography and to science.[5]
