Figure 6. The tongue of Vespertilionoidea, family Vespertilionidae: (a) Posterior region of the tongue with a pair of circumvallate papillae (V) and the conical basal papillae (B) in Histiotus velatus. Note the naked central portion between circumvallate papillae and the glottis (G); (b) Middle portion of the tongue with remarkable salience covered by scale-like filiform papillae with large fungiform papillae in Eptesicus furinalis; (c) Circumvallate papilla, note the lobed surface of the papilla in Eptesicus brasiliensis; (d) Scale-like filiform papillae on the mid-dorsal salience in H. velatus.
