Air-breathing in vertebrates has evolved many times among the bony fish while in water. Its appearance has had a fundamental impact on the regulation of ventilation and acid-base status. We review the physico-chemical constraints imposed by water and air, place the extant air-breathing fish into this framework, and show how that the advantages of combining control of ventilation and acid-base status are only available to the most obligate of air-breathing fish, thus highlighting promising avenues for research.
在水中，脊椎动物的空气呼吸已经在硬骨鱼中多次进化。它的出现对通气和酸碱平衡状态的调节产生了根本性的影响。我们回顾了水和空气所施加的物理化学限制，将现存的空气呼吸鱼类置于这个框架内，并展示了将通气和酸碱平衡状态的控制相结合的优势仅适用于最强制的空气呼吸鱼类，从而突出了有前途的研究途径。
