AbstractThe morphological structure of the tongue and papillae that occur on it vary according to an animal's lifestyle, nutrition, and adaptation to various environmental conditions. This study aimed to reveal in detail the morphological, histological, and electron microscopic structure of the tongue of roe deer (Capreolus capreolus Linnaeus, 1758). In this study, nine roe tongues were used. The tongue consists of three parts: the apex, body, and root. When the dorsal surface of the tongue was examined in detail, five different papillae were observed: filiform, lenticular, conical, fungiform, and vallate. Filiform papillae differed in having secondary papillae according to their localization. The opening holes of taste buds were observed on the surface of the round and flat fungiform papillae. The free ends of the filiform papillae were more pointed and thinner than those of the other papillae, while the width of the lenticular papillae was thicker, the surface was flat, and the free ends were blunt. Triangular‐shaped conical papillae were observed differently regarding the presence or absence of secondary papillae. The vallate papillae were caudolateral to the lingual torus. On the surface of the vallate papillae, circumferenced by a deep groove, were the opening holes of the taste buds and microridges. From this analysis, it appears to be characteristic of roe deer that mechanical function, filiform, and conical papillae contain secondary papillae; lenticular papillae, absent in many deer species, are found; and a prominent papillary groove surrounds all mechanical and gustatory papillae.Research Highlights The lingual papillae of roe deer (Capreolus capreolus Linnaeus, 1758) were examined with this study in detail for the first time. Similarities and differences with ruminant species were determined.
