Abstract

Freshwater bryozoans are unique invertebrates that have complicated life cycles and are sedentary, filter-feeding, colonial organisms. In scientific studies, freshwater bryozoans have gained very little attention. With just 88 species, this group of “moss animals” is spread out among ponds, lakes, streams, and rivers. They widely belong to the freshwater-only phylactolaemate class, while a few species can also be classified as members of the gymnolaemate class, which predominates in marine environments. In this study, we recorded two bryozoan species of Plumatella emarginata and P. geimermassardi for the first time in Valankulam Lake, Coimbatore City, Tamil Nadu, and they were identified and described based on their morphological characteristics.

摘要

淡水苔藓虫是独特的无脊椎动物，具有复杂的生命周期，是久坐、滤食、群居的生物。在科学研究中，淡水苔藓虫很少受到关注。这群“苔藓动物”只有 88 种，分布在池塘、湖泊、溪流和河流中。它们广泛属于仅限淡水的 phylactolaemate 类，而少数物种也可以归类为在海洋环境中占主导地位的 gynolaemate 类的成员。本研究首次在泰米尔纳德邦哥印拜陀市瓦兰库拉姆湖中记录了两种苔藓虫Plumatella emarginata和P. geimermassardi ，并根据其形态特征对其进行了鉴定和描述。
