The inner ear structure of Antimora rostrata and its coupling to the swim bladder were analyzed and compared with the inner ears of several shallow-water species that also have similar coupling. The inner ear of Antimora has a long saccular otolith and sensory epithelium as compared to many other fishes. Some parts of the membranous labyrinth are thick and rigid, while other parts are thinner but attached tightly to the bony capsule. The partially rigid membranous labyrinth, along with its intimate connection to the swim bladder, may help the inner ear follow the sound oscillations from the swim bladder with better precision than would occur in a less rigid inner ear. In addition, the saccular sensory epithelium has an elaborate structure and an anterior enlargement that may be correlated with increased hearing sensitivity. Some of the features in the inner ear of Antimora may reflect the functional specialization of deep-water living and support the hypothesis that there is enhanced inner ear sensitivity in some deep-sea fishes.

深海鱼 Antimora rostrata (Teleostei: Moridae) 的内耳及其与游泳膀胱的耦合。

分析了 Antimora rostrata 的内耳结构及其与鳔的耦合，并与也具有类似耦合的几种浅水物种的内耳进行了比较。与许多其他鱼类相比，安提莫拉的内耳具有长的囊状耳石和感觉上皮。膜迷路的某些部分厚而坚硬，而其他部分较薄但与骨囊紧密相连。部分刚性的膜迷路及其与鱼鳔的紧密连接，可以帮助内耳以比刚性较小的内耳更好的精度跟随鱼鳔发出的声音振荡。此外，囊状感觉上皮具有复杂的结构和前部增大，这可能与听力灵敏度的增加有关。
