The comparative feeding apparatus of Gadidae and Macrouridae has been studied from a functional point of view. Some important modifications in macrourid species in comparison with the gadid ones were found: rostral end of the cranium, rostral ligaments and disposition of the jaw muscles. Anyways, all the modifications seem secondary, motivated by the habitat. That is true in the case of the beak, in relation with the swimming system which had been already observed by Marshall and Bourne (1964). The question of the rostral ligaments modification would be related with the protraction of the upper jaw, but a further analysis is required. Also discussed are two schemes of possible changes in the jaw musculature.
已从功能角度对鳕科和鼠尾鳕科的比较摄食器官进行了研究。与鳕科相比，在鼠尾鳕科物种中发现了一些重要的形态变化：颅骨的吻端、吻部韧带和颌部肌肉的分布。无论如何，所有这些变化似乎都是次生的，是由栖息地所驱动的。喙部的情况确实如此，这与马歇尔和伯恩（1964年）已经观察到的游泳系统有关。吻部韧带变化的问题可能与上颌的前伸有关，但还需要进一步分析。文中还讨论了颌部肌肉组织可能发生变化的两种模式。
