Abstract

The ventilatory action of Siren lacertina and Amphiuma tridactylum were investigated by x-ray cinematography. The lungs are ventilated infrequently. Two fillings of the buccal cavity during exhalation result in the complete collapse of the lungs. One to four fillings of the buccal cavity are required to reinflate the lungs with air on inhalation. The ventilatory cycle lasts 1.016 s in Siren and 4.591 s in Amphiuma. Ventilation mechanisms are compared to those of other amphibians and air-breathing fish.
