在陆生哺乳动物中，鼻腔内的呼吸鼻甲骨骼被用来保存热量和水。为了研究环境温度是否影响斑海豹的呼吸性鼻甲结构，我们使用微型计算机断层扫描技术比较了极地海豹、灰海豹和僧海豹的上颌鼻甲骨骼形态。极地海豹的上颌鼻甲比僧海豹有更大的表面积，这是由于极地海豹在更大的鼻腔中有更密集、更复杂的鼻甲。灰海豹是中间的；这一物种的幼体被证明比同种成体具有更密集的上颌鼻甲，具有更短的分枝长度。在所有封闭物中，上鼻甲质量最密集部分的分维非常接近2，表明这些卷曲的骨骼均匀地填满了可用的空间。与僧海豹相比，极地海豹的上鼻甲系统要复杂得多，这与限制呼吸热损失的更大需求是一致的。
In terrestrial mammals, the respiratory turbinate bones within the nasal cavity are employed to conserve heat and water. In order to investigate whether environmental temperature affects respiratory turbinate structure in phocids, we used micro-computed tomography to compare maxilloturbinate bone morphology in polar seals, grey seals and monk seals. The maxilloturbinates of polar seals have much higher surface areas than those of monk seals, the result of the polar seals having more densely packed, complex turbinates within larger nasal cavities. Grey seals were intermediate; a juvenile of this species proved to have more densely packed maxilloturbinates with shorter branch lengths than a conspecific adult. Fractal dimension in the densest part of the maxilloturbinate mass was very close to 2 in all seals, indicating that these convoluted bones evenly fill the available space. The much more elaborate maxilloturbinate systems in polar seals, compared with monk seals, are consistent with a greater need to limit respiratory heat loss.
