Anatomy data of Crassostrea collected on Rio Grande do Sul, Brazil

This dataset contains the continuous and discrete anatomical data of Crassostrea rhizophorae and C. gasar which were measured after the specimens' identification through polymerase chain reaction-restriction fragment length polymorphism analysis and mitochondrial rDNA sequencing of the 16S rRNA. Based on the molecular identity of the specimens, a comparative anatomical assessment of the size of the mantle, size of the labial palps, shape of the accessory heart, shape of the heart, shape of the anus, and the pattern of tentacles on the edge of the mantle was conducted in Rstudio program.  Data related to the anatomy of the species are plastic and are incapable of generating specific criteria for the identification of C. gasar and C. rhizophorae. 

本数据集包含红树林牡蛎（Crassostrea rhizophorae）与加萨牡蛎（C. gasar）的连续型与离散型解剖学数据。所有测量数据均取自经物种鉴定后的样本，样本鉴定采用聚合酶链式反应-限制性片段长度多态性（polymerase chain reaction-restriction fragment length polymorphism）分析及线粒体16S核糖体RNA（16S rRNA）测序技术。基于样本的分子鉴定结果，研究人员依托RStudio程序，对两种牡蛎的外套膜尺寸、唇瓣尺寸、副心脏形态、心脏形态、肛门形态以及外套膜边缘触手分布模式开展了对比解剖学评估。本数据集所涉及的物种解剖学特征具有可塑性，无法为C. gasar与C. rhizophorae的物种鉴定提供特异性判定标准。
