Invertebrate collections

The basic part of the collection contains about 200,000 storage units. As the latter may include both separate specimens and plankton or benthic samples, the actual number of individual specimens stored in the Section exceeds 2,000,000. These materials belong to 22 phyla and about 55 classes.

The forms of collection materials include “dry” specimens (shells etc.), “wet” specimens preserved in alcohol or formalin, and collection of micropreparations.

The main sources of collections growth are both the museum and academic institutions field works, also materials come from universities, etc. Many of the materials were obtained due to exchange with other museums. A significant contribution to completion of some invertebrate groups is made by donators.

Relatively high complexity of the invertebrate collections defines complexity of their registration system. Its basic forms are common for the museum, they are “Book of entries”, “Inventory books” and systematic catalogues, but the entire documentation is more dispersed and bulky. Recently, electronic databases for some of the larger parts of the collection has been started.
