| 摘 要： | 角质颚是研究头足类各种生物信息的重要组织，为实现头足类角质颚色素沉积的精确化测量，探究色素沉积在头足类角质颚判别分类中的作用，研究选取茎柔鱼、柔鱼以及翼柄柔鱼3种头足类生物的角质颚下颚为研究对象，以其侧视图像为基础，对其色素沉积按照等级Ⅰ：黑色、等级Ⅱ：灰色、等级Ⅲ：浅灰色、等级Ⅳ：透明四个等级进行可视化，分别计算出茎柔鱼、柔鱼以及翼柄柔鱼角质颚四种等级的色素沉积面积与头盖-翼部区域以及脊突-侧壁区域面积的比例关系，并且采用逐步判别分析法对3种头足类角质颚之间的色素沉积差异进行分析，结果显示等级Ⅰ、Ⅳ在脊突、侧壁区域各色素梯度占比对判定分类的结果具有显著意义，判别成功率为74.4%。研究认为，3种头足类的角质颚色素沉积情况存在一定差异，而这些差异有可能是由于3种头足类不同的生活特性和摄食习惯导致。研究实现了角质颚色素沉积的数值化和色素沉积等级的精确化划分，并按照划分的结果，将色素沉积情况作为全新的定量测量方法，为头足类生物角质颚色素沉积研究提供了新的思路。

| Abstract: | Cephalopod beaks are important materials for the study of cephalopod organisms. In order to achieve the accurate measurement of pigmentation of cephalopod beaks and to investigate the role of pigmentation in the discriminative classification of cephalopod beaks. The study selected the beak of three cephalopods, the Middle East Pacific Dosidicus gigas, the northwest Pacific Ommastrephesbartrami and the Middle East Atlantic Ommastrephespteropus.The pigmentation is visualised on the basis of its lateral view image according to four classes: class I: black, class II: grey, class III: light grey and class IV: transparent.The ratio of the area of pigmentation to the area of the hood-wing region and the area of the crest-lateral wall region was calculated for the four classes of Dosidicus gigas, Ommastrephesbartrami and Ommastrephespteropus, respectively.The difference in pigmentation between the three cephalopods was analysed using stepwise discriminant analysis, and the correct rate of discrimination was 74.4%.It is suggested that there are some differences in the pigmentation of the beak of the three cephalopods, and that these differences may be due to the different life characteristics and feeding habits of the three cephalopods.The study achieves numerical and precise classification of pigmentation classes in Cephalopod beak, which is a new quantitative measurement method and provides new ideas for the study of pigmentation in Cephalopod beak. |
