The Museum of Zoology and Comparative Anatomy boasts a collection that includes about 3,500 naturalised vertebrates (birds, mammals, fish, reptiles), of which about one hundred belong to the vertebrate fauna of the Modena area, about 1,000 vertebrates preserved in liquid (fish and reptiles in particular), 250 skeletons and anatomical parts of vertebrates, and several hundred invertebrates preserved in alcohol or formalin. The malacological and entomological collections are also remarkable. Of particular interest is the Franchini Collection, a rich collection of parasitic and poisonous animals, and the ornithological collection of psittaciformes (parrots).
