蟹守螺总科软体动物的系统分类学研究进展

蟹守螺总科(Cerithioidea)是一群古老、极度多样化的腹足类,广泛分布于全球热带至温带的水域中,是腹足类生态和进化研究中重要的关键群体。目前蟹守螺总科动物整体上属于了解较少的类群,其定义也一直在修订中。随着贝类学研究理念的进步与技术手段的发展,蟹守螺总科的分类学与系统发育学研究等有了较大进展,但仍然有许多问题亟待解决。文中对该总科的国内外研究现状和存在的问题进行了研究综述。

Progress of systematic studies on Cerithioidea (Mollusca, Gas-tropoda, Caenogastropoda)

The cerithioids are an ancient and extremely diverse group of gastropods, with a wide geographical distribution in almost all aquatic habitats from tropical to warm temperate regions worldwide. Cerithioidea is considered to be an important keystone group for understanding the ecology and evolution of gastropods. However, Cerithioideans are less understood, and impressed by the modification of their definition from time to time. With the development of concept and techniques in malacology, remarkable progress was achieved in taxonomy and phylogenetic analysis of cerithioids. The status and problems existed in Cerithioidean research are reviewed in this paper.
