We examined the dorsal lingual surfaces of an adult sitatunga (Tragelaphus spekei) by scanning electron microscopy. Filiform, fungiform and vallate papillae were observed. The filiform papillae consisted of a larger main papilla and smaller secondary papillae. The filiform papilla contained connective tissue core consisting of several processes. The fungiform papillae were round in shape. The connective tissue core of the fungiform papilla was flower-bud shaped. Lenticular papillae were limited on the torus lingua. The connective tissue core of the lenticular papilla consisted of numerous small spines, or these spines and rod-shaped processes. The vallate papillae were flattened-oval shaped and the papillae were surrounded by a circular trench. The connective tissue core of the vallate papilla was covered with numerous small spines. These findings indicate that the tongue of the sitatunga is similar to that of the blackbuck and Barbary sheep.
