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.
我们通过扫描电子显微镜检查了一只成年水羚（Tragelaphus spekei）的舌背表面。观察到丝状乳头、菌状乳头和轮廓乳头。丝状乳头由一个较大的主乳头和较小的次乳头组成。丝状乳头含有由几个突起组成的结缔组织核心。菌状乳头呈圆形。菌状乳头的结缔组织核心呈花蕾状。豆状乳头局限于舌隆突上。豆状乳头的结缔组织核心由许多小刺或这些刺和杆状突起组成。轮廓乳头呈扁平椭圆形，乳头被圆形沟包围。轮廓乳头的结缔组织核心覆盖着许多小刺。这些发现表明水羚的舌头与印度羚和蛮羊的舌头相似。
