依据索引收录的作者摘要概括。
Summary based on the indexed author abstract.
多种鲨鱼的比较研究中包含皱鳃鲨 Chlamydoselachus anguineus 的专门分析。
Contains a dedicated Chlamydoselachus anguineus analysis within a multi-species shark study.
主要发现 Key findings
涵盖九目鲨鱼的定量CT显示，内骨骼矿化程度在物种间差异显著，与栖息深度等生态因素的关联强于亲缘关系。
Quantitative CT across all nine shark orders shows substantial interspecific variation in skeletal mineralization, associated more strongly with ecology such as habitat depth than with phylogeny.
结论 Conclusions
软骨骨骼的矿化并非固定的原始状态，而可能反映浮力与能量利用等适应。
Cartilaginous skeletal mineralization is not a fixed primitive condition and may reflect buoyancy and energetic adaptations.
