Non-invasive computed tomography (CT) of an adult sand tiger shark Rafinesque, 1810 is used to provide an interactive three-dimensional 'general' shark (Selachimorpha) anatomy atlas. Given its post-cranial body morphology, the sand tiger shark appeared to be a well-chosen candidate and through comparison of the sand tiger shark with several other representatives of all eight established orders of sharks, we confirm that the relatively large degree of mineralization of the endoskeleton, along with the overall size, makes the sand tiger shark an ideal candidate for skeletal segmentation and construction of a skeletal atlas using conventional CT. This atlas both increases accessibility to the internal morphological features of the sand tiger shark and provides a more generalized overview of the skeletal anatomy of sharks and can aid as a supplement to destructive fresh dissection of specimens in the future and the construction of future skeletal atlases of other less mineralized sharks.
利用对一条成年沙虎鲨（噬人鲨属，1810年）进行的非侵入性计算机断层扫描（CT），构建了一个交互式三维“通用”鲨鱼（鲨形目）解剖图谱。鉴于其颅后身体形态，沙虎鲨似乎是一个精心挑选的候选对象。通过将沙虎鲨与鲨鱼所有八个既定目里的其他几种代表物种进行比较，我们证实，内骨骼相对较高的矿化程度以及整体体型，使得沙虎鲨成为使用传统CT进行骨骼分割和构建骨骼图谱的理想候选对象。该图谱既增加了对沙虎鲨内部形态特征的可及性，又提供了对鲨鱼骨骼解剖结构更具普遍性的概述，并且在未来可作为对标本进行破坏性新鲜解剖的补充，以及构建其他矿化程度较低鲨鱼的未来骨骼图谱的辅助工具。
