摘要：

Results of the morphological analysis of ecology and feeding of two sympatric forms of whitefishes (lacustrine and lacustrine-riverine) inhabiting Lake Taymyr (the Taymyr Peninsula) are presented in the article. It is revealed that these forms do not differ in the number of gill rakers on the first branchial arch and in the number of perforated scales in the lateral line, but they do differ in plastic characters, spawning periods, and area. At the age of 2-3 years they become separate in regards to feeding type. It is assumed that both forms of whitefishes inhabited Lake Taymyr simultaneously with the filling of the lake basin. Apparently the taxonomic status of the sympatric whitefishes from Lake Taymyr is broader than the term "ecological form.".
