title: The scanning electron microscopic study of lingual papillae in the silver fox (Vulpes vulpes fulva, Desmarest, 1820).
abstract: The tongues of adult silver foxes were studied using scanning electron microscopy. Five types of lingual papillae were found on the dorsal surface of the tongue. The most numerous papillae were filiform papillae covering the apex and body of the tongue. The filiform papillae on the anterior part of the tongue are divided into 1 main and 10-12 accessory processes. In the posterior part of the body of the tongue the number of accessory processes is reduced. Fungiform papillae are located between the filiform papillae. A cluster of 12 large fungiform papillae was found on the apex of the tongue. Conical papillae are located in the area of the vallate papillae and cover the posterior part of the root of the tongue. Their size increases towards the pharynx, where they are distributed more sparsely. In the silver foxes there were two pairs of vallate papillae. The wall surrounding each papilla and its gustatory trench forms partly connected 6-8 conical papillae. The foliate papillae on both margins of the tongue body are small and consist of 4-5 laminae. The distribution and type of lingual papillae found in the silver fox are similar to those in the other species belonging to the family Canidae.
