Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g specimen, to 30 ml O2kg-1 h-1, in a 255 g specimen. 3. While the combined O2 uptake changed by a factor of 2, within the weight range under study, the aquatic O2 uptake changed 8-fold within the same range. The smaller fish satisfy 70% of their O2 requirement by aquatic breathing compared to 10-15% in the grown specimens. 4. The pattern of bimodal breathing in P. amphibius is discussed in relation to the natural habitat of the species.

已测量了非洲肺鱼原鳍鱼摄取空气和水中氧气的量与体重的关系。2. 空气和水中氧气的联合摄取量范围为：3至7克的标本中为60毫升氧气每千克每小时标准温度和压力干燥状态，255克的标本中为30毫升氧气每千克每小时。3. 在研究的体重范围内，联合氧气摄取量变化了2倍，而在此相同范围内，水生氧气摄取量变化了8倍。较小的鱼通过水生呼吸满足其70%的氧气需求，而成年标本中这一比例为10 - 15%。4. 结合该物种的自然栖息地，讨论了原鳍鱼的双峰呼吸模式。
