Abstrakt: Nowadays the processes of crossing of different mammalian species are well characterized in light of genetics, and possibility of reproduction. Generally, lack detailed studies on changes in anatomy and histology of internal systems of hybrids. Bison bonasus hybrid is an interspecific species between the bull of European bison (Bison bonasus), and female of domesticated cattle (Bos taurus). To study the anatomy of tongue and distribution of lingual papillae on Bison bonasus hybrid tongue, a stereomicroscopic and scanning electron microscopic observations was conducted. We aimed to study the appearance of macro- and microscopic traits in relation to parental species and other bovids. Results indicate that Bison bonasus hybrid tongue possesses characteristic traits for parental species and ruminants from Bovidae family and also species-specific features differ from mentioned animals. Specific new traits in hybrid are: V-shaped arrangement of lingual papillae on ventral surface of the tongue, rosette arrangement of conical papillae on the top of lingual prominence, bigger number of vallate papillae and closer arrangement of vallate papillae. In hybrid observed also the appearance of combination of parental traits. Similar to European bison are rectangular shape of lingual prominence and absence of filiform papillae on the root of tongue. Presence of lateral processes of filiform papillae on the apex of tongue, and arrangement of vallate papillae into two rows corresponded to cattle. Development of new morphological features of tongue and its mucosal papillae in Bison bonasus hybrid opens new issue for future studies on organs of digestive system in animals after hybridization.
