Who knew feet could be so interesting?  Arndt is both author and photographer in this compilation of the feet of various animals.  The feet are divided into groups according to how they move: walk, climb, swim or dig, an interesting approach.  Many of the photographs have captured the animal’s foot against a pure black background, the contrast making the textures stand out more noticeably.  No table of contents and the index is arranged by the various animals’ feet shown.
