摘　　要：头足类的眼睛晶体是除耳石、角质颚和内壳之外又一重要的硬组织,其形态结构稳定、易提取、易保存,记录了头足类的大量生物与生态学信息,是研究头足类生活史过程的有益补充。尽管眼睛晶体在年龄鉴定和微量元素分析方面相比耳石和角质颚没有优势,但是在稳定同位素分析方面优势明显。本研究中从眼睛晶体的尺寸、微结构、微量元素和稳定同位素等方面,回顾了其在头足类年龄、生长、摄食、栖息和洄游等基础生活史过程中的应用。综合分析认为,尽管眼睛晶体适合从时间序列上准确的分析头足类的生活史信息,今后的研究仍需要准确掌握眼睛晶体生长纹的周期性,在此基础上确定各层断面形成的确切时间、年龄,进而重建头足类的栖息、洄游和摄食等生活史信息。The eye lens, as one of the most important hard structures characterized by stale morphology, easy ex- traction and preservation in Cephalopoda, record lots of biological and ecological information, and is of supplemen- tary material, besides beak, statolith and inner shell, to investigate cephalopod life history. According to published data, eye lens can be used to estimate cephalopod age and growth, and elemental signatures and stable isotopes are considered to be useful for reconstructing cephalopod habitat, migration and feeding ecology. Accurate grasp of the growth periodicity of eye lens is still required in future research to determine the exact time and age of each section, and to reconstruct life history information of cephalopods including habitat, migration and trophie ecology, although the eye lens have advantage in age determination in time series.
