Mammals and birds are stored both as mounted specimens or prepared skins, or they are represented in the egg, cranial or antler collections. Insects are pinned or stored in ethanol. All specimens are labeled holding information such as date of collection, locality, collecting method. The museum has a separate type collection. This collection holds type specimens used in original descriptions of new species. 

Specimens are mainly from the 20th century, but a few are more than 200 years old. New specimens are added to the collection from research projects and field trips targeting poorly known groups or geographic areas where knowledge of local fauna is scarce. Some of the collections have received donations from private collectors.

A newly established tissue collection store tissue samples that can be used for DNA and toxicology analyses. 

Approximately 90 % of the collections are registered in the collections database ZOOTRON.
