Ernst Haeckel was exceptionally talented. His work occupies a unique position in history, lying in the interface between zoology, Darwinism, philosophy and art. He discovered, described and drew thousands of unknown species such as radiolaria and immortalised them in publications. In our collection, we honour Haeckel’s achievements with images such as ‘Actiniae’ (sea anemones), ‘Sea Snails’ and ‘Jellyfish Species’.
