Arm segments from Ophiocoma pumila. The 3D data included here were generated from x-ray tomography scans of specimens of brittle stars Ophiocoma wendtii, Ophiocoma echinata and Ophiocoma pumila. For full methodology, please refer to the Method Details text. All models are downsized for practicality in PDF form; STL files with full detail are available on request. 3D files require Adobe Acrobat or Acrobat Reader (v. 7 or higher) for full interactive functionality. Use left-click to rotate, Ctrl+click to pan, and shift+click to zoom. Default view is the dorsal surface.

紫孔蛇尾（Ophiocoma pumila）的腕节段。本次收录的三维数据源自三种海蛇尾标本的X射线断层扫描（X-ray tomography）：温氏蛇尾（Ophiocoma wendtii）、棘蛇尾（Ophiocoma echinata）以及紫孔蛇尾（Ophiocoma pumila）。完整实验方法请参阅方法详情文本。为适配PDF展示的实用性，所有模型均已做尺寸精简；完整细节的STL文件可按需获取。三维文件需使用Adobe Acrobat或Acrobat Reader（7.0及以上版本）方可实现完整交互功能。操作方式如下：左键点击旋转视图，Ctrl+左键点击平移视图，Shift+左键点击缩放视图。默认视图为背侧表面。
