The St.-Petersburg zoological museum is one of the largest museums of its kind in the world. At present there are 30.000 animal species on permanent display. Collections of Polyarctic and particularly Central Asian mammoths and their flora are unique: most noteworthy are the skeletons and bodyfragments preserved in permafrost.
The Museum was founded as a separate academic institution in July 1832. In 1930, the Zoological Institute of the Russian Academy of Sciences was organized on the basis of the Museum's collections. Currently approximately 40,000 animals are included in the exhibitions of the Museum, and its scientific collections include more than 15,000,000 specimens. The exhibitions of the Museum are organized in two parts, systematic displays and ecological dioramas. The systematic exhibition was formed before 1930, and new exhibits have been added as a result of expeditions by staff of the Zoological Institute. The greatest changes in the systematic exhibition took place between 1947 and 1954, when the Museum was headed by Prof. V. B. Dubinin. The identity of all exhibited specimens was reevaluated and new label texts were prepared during the period from 1954 to 1964, when the Museum was headed by Prof. A. I. Ivanov.
