形态特征是大多数动物的主要识别特征，也是许多比较生理学研究的关键，但目前用于保存和记录软体海洋动物的技术在质量和可及性方面受到限制。数字记录可以补充物理标本，具有广泛的应用范围，从物种描述到运动学建模，但缺乏创建软体半透明水下动物模型的选择。我们开发了一种基于实验室的技术，可以在几秒钟内实时扫描半透明的水下动物和物体。为了演示该方法，我们生成了一个已知尺寸的对象的完整三维重建（3DR）进行验证，以及两个活的海洋动物-管水母和片足类动物-允许对每个进行详细测量。像这样的技术为更快的数据采集、综合和比较定量方法以及更容易获得的脆弱和稀有生物样品的收集铺平了道路。
Synopsis Morphological features are the primary identifying properties of most animals and key to many comparative physiological studies, yet current techniques for preservation and documentation of soft-bodied marine animals are limited in terms of quality and accessibility. Digital records can complement physical specimens, with a wide array of applications ranging from species description to kinematics modeling, but options are lacking for creating models of soft-bodied semi-transparent underwater animals. We developed a lab-based technique that can live-scan semi-transparent, submerged animals, and objects within seconds. To demonstrate the method, we generated full three-dimensional reconstructions (3DRs) of an object of known dimensions for verification, as well as two live marine animals-a siphonophore and an amphipod-allowing detailed measurements on each. Techniques like these pave the way for faster data capture, integrative and comparative quantitative approaches, and more accessible collections of fragile and rare biological samples.
