Exhibition of Invertebrates
The animal kingdom is divided, based on having a backbone, into two groups: invertebrates (Avertebrata) and vertebrates (Vertebrata). Invertebrates make up about 95% of all animal species discovered so far. The exhibition Invertebrates, in the permanent exhibition of the Department of Natural Sciences, reflects the abundance and richness of the world of invertebrates.
In terms of its historical and scientific value, as well as the number of exhibited specimens, the entomological collection occupies a special place. The exhibited collection of about 16,000 insects represents only a part of the scientific entomological collection, and is one of the richest and most significant collections of this kind on the Balkan Peninsula. It has two units: Insects of the Balkan Peninsula and Exotic insects.
The collection of Molluscs of the Balkan Peninsula brings 80 characteristic representatives of the terrestrial and freshwater malacofauna of the Balkans, while the collection of Molluscs of the non-Balkan area exhibits about 50 species from the rest of the world. 182 types of snails and shells from the Mediterranean, which make up the collection of the same name, are displayed in two showcases. In the Aquatic, Terrestrial and Parasitic Invertebrates collection, 55 species of these invertebrates are exhibited, and in the Arthropoda collection, there are 37 species of scorpions, crustaceans and spiders.
