|The zoological collections, founded in 1735, are among the oldest and largest in Northern Europe. There are some 10 million specimens of which the vast majority are insects. The annual acquisition is approximately 30 000 specimens.
The holdings include large collections of type material. There are approximately 15 000 insect types, 150 vertebrates and 1 400 invertebrates, other than insects. Important insect collections, holding type material, are Zetterstedt's, Fallén's, Dahlbom's, and Thomson's among others. Vertebrates are mainly Pisces and Reptilia. One important collection of invertebrates is Oscar Carlgren's Anthozoa collection which includes 66 types.
There is also a small exhibition of taxonomical and historical interest, open to the public by appointment.
