By law the Museum is prohibited from parting with any specimen that has been registered in the collection. The creation of a display requires the involvement of scientist, architect, artist, taxidermist, photographer, label writer, lighting expert and cabinet maker. Among the special factors to be considered is the preservation of specimens against damage by insects, moisture or the ultra-violet rays in light. Various skills and techniques are employed in preparing the objects that go into museum displays. Taxidermists, who prepare perishable plant and animal material, require special knowledge about the anatomy and movement of animals which they sculpture and cast.
Modellers use similar skills in creating scale models.
Artists and photographers provide the backgrounds to dioramas and settings for objects, and illustrate important features and details. Modern displays demand high standards and the advent of audio visual installation has contributed substantially towards this.
