'''''Kunstformen der Natur''''' ([[
According to Haeckel scholar Olaf Breidbach (the editor of modern editions of ''Kunstformen''), the work was "not just a book of illustrations but also the summation of his view of the world." The over-riding themes of the ''Kunstformen'' plates are symmetry and organization. The subjects were selected to embody organization, from the scale patterns of [[boxfish]]es to the spirals of [[ammonite]]s to the perfect symmetries of jellies and microorganisms, while images composing each plate are arranged for maximum visual impact.<ref>Breidbach, ''Visions of Nature'', pp 229-231</ref>
A second edition of ''Kunstformen'', containing only 30 of the prints, was produced in 1924.
