The introductory part considers the terms zoonym, zoonomy, -onym and appellative, determining the ways of defining the term zoonym and its difference in meaning in relation to the term appellative. Then it defines the methods and criteria used for the purpose of excerption and analysis of excerpted zoonyms, with a special attention paid to the status of zoonyms (in relation to appellatives and other categories of onomastics) in Vuk's Rječnik. Zoonyms determined this way are divided in the central part of the paper into the motivated and non-motivated, while the motivated zoonyms were sorted into three lexical-semantic groups: according to the color of the entire body of animal, the color of one part of the body of animal and a dominant trait of animal that is not conditioned by color. Zoonyms within these groups are further divided into subgroups according to the traditional classifications of Serbian lexicology of zoonyms. In the final part of the paper, there is a final review of the status of zoonyms in Vuk's Rječnik, as well as the state of zoonyms as a lexical stratum within the contemporary and current research of onomastics of the Serbian language.
