The nasolaryngeal system of the bottlenosed dolphin (Tursiops truncatus) is complex and highly specialized for respiration and sound production. The exact source and mechanism of sound production by dolphins is not understood. Electromyographic studies are essential for understanding the functional anatomy and mechanisms of sound production. Dissections and measurements have been made for the purpose of identifying external landmarks and other details necessary for inserting electrodes in the muscles of the nasolaryngeal area. Based upon these anatomic investigations, some functions of this musculature have been suggested, and the first electromyographic studies of dolphin acoustic mechanisms have been initiated.
