ERNST HAECKEL: ART FORMS IN NATURE
ECHINIDEA: Igelsterne (Echinodermata: Echinoidea)
This plate shows the life cycle of sea urchins from larva to adult. The two month-old urchin stage center with its long, symmetrical, kinetic projections is only a millimeter long. Haeckel's detailed depiction of the intricate forms and of the process of cell division is a credit to advances in design of the microscope, especially the apochromatic lens system, developed in 1868 by Ernst Abbe.
