朱鹮的前、后肢比较解剖学观察

用解剖学方法对朱和白的前、后肢进行了比较，发现他们的前肢各部分长度差异不大，白略长。后肢各部分长度差异较大，白后肢各部分：股骨部、小腿、附跖部、趾部骨骼均比朱粗壮，并分别比朱长９％，３５．２％，７１，４０％～４３％。利于在稻田、小河、湖水边较深地方采食。白的前、后肢的肌肉也比朱发达。在体重差别较大的情况下，体重轻的白肌肉仍比朱发达，这样更利于飞翔。因而，朱没有白的生存适应性强。

A Comparative Anatomic Observation of the Thoracic Limb and Pelvic Limb in Crested Ibis

The thoracic limb and pelvic limb were compared between crested ibis and white ibis. It is discovered that there is not much obvious difference in the thoracic limb, of which white ibis is slightly longer, but the difference in the pelvic limb is obvious, in which each part of the bones such as thigh, leg, pes and digit in white ibis are stronger and 9%, 35.2%, 71%, 40%43%, respectively longer than those in crested ibis. Those are helpful to eat on rice field, small river and lake. Moreover, the muscles in the thoracic limb and pelvic limb are more developed in white ibis than in crested ibis. In view of to the weight of the white ibis which is lighter than crested ibis, that are in favor of flying. Thus it was concluded that the adaptability of white ibis is lower than crested ibis.
