Micro-CT Morphological Data of Glycera tridactyla Schmarda, 1861 and Phascolosoma (Phascolosoma) stephensoni (Stephen, 1942) species

This dataset comprises morphological data for two annelid species, the polychaete Glycera tridactyla Schmarda, 1861, and the sipunculan Phascolosoma (Phascolosoma) stephensoni (Stephen, 1942), obtained using micro-computed tomography (micro-CT). Several parameters related to the eversion mechanism of the pharynx in Polychaeta and the introvert in Sipuncula were estimated through two- and three-dimensional analyses of micro-CT datasets from specimens in different body configurations.

本数据集涵盖两种环节动物的形态学数据，分别为多毛纲（Polychaeta）的Glycera tridactyla Schmarda, 1861，以及星虫动物门（Sipuncula）的Phascolosoma (Phascolosoma) stephensoni (Stephen, 1942)，所有数据均通过显微计算机断层扫描（micro-CT）获取。研究人员通过对处于不同身体构型的标本的micro-CT数据集开展二维与三维分析，估算得到与多毛纲动物咽外翻机制、星虫动物门翻吻相关的多项参数。
