Description
We examined the dorsal lingual surface of an adult black-backed jackal (Canis mesomelas) by using scanning electron microscopy. The filiform papilla on the lingual apex exhibited a crown-like shape with several pointed processes. The connective tissue core of the filiform papilla was U-shaped. The filiform papillae on the lingual body had several pointed processes. The connective tissue core of the filiform papillae consisted of one large and several small conical papillae. The fungiform papillae on the lingual apex and body had a smooth surface. The connective tissue core of the fungiform papillae was not hollow and did not have processes. The vallate papillae were surrounded by a groove and pad with many processes on the surface. The connective tissue core of the vallate papillae had many ditches. Thus, the tongue of the black-backed jackal more closely resembles that of the bush dog than those of the raccoon dog or fox.
