The Zoological Collection of the University of Vienna is a scientific reference collection which covers almost the entire animal kingdom. It comprises an estimated 500.000 specimens which are worldwide in origin but with an emphasis on the territory of the former Austro-Hungarian Empire. Its resources include alcohol-preserved anatomical, embryological and whole-mount preparations, vertebrate and invertebrate skeletons as well as some rare and historic scientific models from Blaschka (glass models of marine animals), Frič, and Ziegler (wax models), last but not least the scientific wall chart collection.
