Eremophilus mutisii uses the vascularized central portion of its stomach for aerial respiration, and is a frequent but not obligatory air breather. Air ventilation takes place during a rapid dash to the surface with the expiration of old air preceding inspiration. The frequency of air breathing is affected by aquatic O2 concentration. E. mutisii can survive at least 10 days without air breathing in normoxic water but cannot survive without air access in water containing less than 2.0 ppm O2.
穆氏真蚓利用其胃部的血管化中央部分进行空气呼吸，是一种常见但非必需的空气呼吸者。空气交换在快速冲向水面时发生，旧空气在吸气前呼出。空气呼吸的频率受水中氧气浓度的影响。在常氧水中，穆氏真蚓至少可以在不进行空气呼吸的情况下存活10天，但在含氧量低于2.0 ppm的水中，如果无法接触空气则无法存活。
