当从卵膜中取出时，爪蟾胚胎可以游泳。高速摄影显示，在游泳时，横向波动通过喙尾向下的身体。游泳的节奏周期是40-100毫秒。在游泳，肌节肌肉的电活动交替对侧的一段和扫描同侧肌节的喙尾。检查肌节肌肉生理学。肌肉纤维彼此电耦合，并且纤维能够尖峰。在游泳的肌节传导通路的可能作用进行了讨论。
When removed from their egg membranes, Xenopus embryos can swim. High-speed cinematography shows that, in swimming, lateral undulations pass rostro-caudally down the body. The swimming rhythm period is 40-100 ms. In swimming, electrical activity in myotomal muscles alternates on opposite sides of a segment and sweeps rostro-caudally in ipsilateral myotomes. Myotome muscle physiology was examined. Muscle fibres are electrically coupled to each other, and the fibres are able to spike. The possible role of a myotomal conduction pathway in swimming is discussed.
