Right nasal cavity (A) and its flexible rostral portion (B) of an adult male dhole.

Abstract

<p>(A) Middle nasal concha and nasal septum removed to expose the dorsal, the alar and the basal folds. ** = cut edge of the nasal septum. (B) Detail of (A). The arrow points to the flexible rostral portion of the nose, which can be variably constricted by differential action of the rostral nasal muscles. This will narrow particularly the space between the dorsal and the alar folds and, in concert with movements of the nostril wings, might influence nasal call characteristics. Mediosagittal section of the nasal region, right half, medial view. Scale bar = 10 mm in (A) and (B), respectively.</p
