The exhibition is a combination of eight main halls in which exhibits from all around the world as well as a live exhibition are displayed. The main halls are as follows: “Minerals“, “Paleontology“ (a new hall constructed in 2016), “Botany“, “Invertebrates“, “Fish“, “Amphibians and Reptiles“, “Birds“ and “Mammals”. Since 2015, the museum has had a new exhibition plan, introduced by chief assistant Dr Ognyan Todorov, in which the vertebrates are systematically arranged and presented in artificially created habitats resembling environment in which they live. To this end, the windows have an increased capacity in order to recreate the habitats of the species with a maximum resemblance. The live exhibition is housed in the Troyan hall, arranged as a tropical jungle with live plants and butterflies.

Junior trainee at the museum Teodor Yonov (aged 10) will deliver a public presentation about dinosaurs at the Planetarium. Teodor already participated in a similar event as part of the programme of the Young Blue Earth youth creation festival in April 2018. His presentation Ten animals we are glad are extinct aroused strong interest and inspiration in the audience.
