Means, standard deviations and coefficient of variation of Crown Width (CW) and Average Ridge Distance (ARD) in drag reduction scales of ten different species of thelodonts.

For comparison, the same data have been compiled for 14 species of extant sharks belonging to the two different ecological groups of strong-swimming pelagic sharks (fast pelagic hunting species and large near-shore hunters following the ecological classification of Reif [15]). Correlation analysis results between CW and ARD are given for each species of thelodonts.

为便于对比，本研究依照Reif[15]提出的生态分类标准，针对14种隶属于强游泳远洋鲨鱼两个不同生态类群的现生鲨鱼（即快速远洋捕食物种与大型近岸捕食者）汇编了相同的数据集。本研究给出了每一种骨甲鱼类的CW与ARD之间的相关性分析结果。
