Aardvarks have a superficial resemblance to a long snouted pig.
The skin is thick, sparsely covered by hairs and varies in color from dull brownish gray to dull yellowish gray. The blunt snout has circular nostrils. The tongue is tapered. The cheek teeth are composed of numerous hexagonal prisms of dentin, which are perpendicular to the occlusal surface. Each prism is pierced by a tubule that is homologous to the pulp cavity, not the Tomes fibres.
