Le larynx du phoque de Weddell (Leptonychotes weddelli, Lesson, 1826)
A descriptive and functional study of cartilages, muscles, and cavities of the Weddell seal larynx is made.Several conclusions can be drawn from this study, (a) The glottis is, more than in other pinnipeds, better adapted toward protective closure of the larynx, (b) The membranous part of the vocal...
