Plate 93 from Ernst Haeckel's visually dazzling Kunstformen der Natur, the Art Forms of Nature, published in 1904. With the assistance of Jena artist-lithographer Adolf Giltsch, Haeckel produced one hundred plates depicting the forms of animal life, mainly marine animals. With this book Haeckel wanted to create an 'aesthetics of nature' and to show how the incessant struggle for existence he had learnt from Darwin was in fact producing an endless beauty and variety of forms - Darwin and Humboldt combined together.
