Hundreds of planarian species exist worldwide, representing a rich phenotypic diversity. This chapter presents an overview of the morphology and anatomy of various taxonomic groups of planarian flatworms, focusing on features enabling recognition and identification of the animals. The most recent view on the phylogenetic relationships of the planarians is presented, together with geographic distribution patterns of major groups of triclads. The chapter concludes with a brief methodological section outlining species identification on basis of anatomical features. In conjunction with the established laboratory model species, the phenotypic diversity of planarians provides rich opportunities for comparative studies, which this chapter aims to inspire.
全球存在着数百种涡虫物种，呈现出丰富的表型多样性。本章概述了涡虫扁形虫各分类群体的形态学和解剖学，重点关注有助于识别和鉴定这些动物的特征。文中介绍了关于涡虫系统发育关系的最新观点，以及主要三肠目群体的地理分布模式。本章最后有一个简短的方法部分，概述了基于解剖特征进行物种鉴定的方法。结合已确立的实验室模式物种，涡虫的表型多样性为比较研究提供了丰富的机会，本章旨在激发这方面的研究。
