Abstract

Freshwater Bryozoa is one of the less explored or ignored animal groups from India. Kagzipura Lake, a rainwater fed water body was surveyed for three years to understand the diversity and distribution of bryozoan fauna. The present study depicts four Phylactolaemata bryozoans species as Rumarcanella vorstmani, Plumatella casmiana, Lophopodella carteri and Swarupella divina. The manuscript provides brief descriptions of these species, photomicrographs of statoblasts using scanning electron microscopy and colony characteristics.

Highlights

  • Freshwater Bryozoa is one of the less explored or ignored animal groups from India

  • Some statoblasts were stored in the aquarium for germination study while the remaining were stored in 70% alcohol for Scanning electron microscopy (SEM) analysis

  • Rumarcanella vorstmani floatoblasts are nearly symmetrical laterally, small and short with sides briefly parallel near the centre and the ends broadly rounded, both fenestrae bear small tubercles with hypertubercles, they have irregular annulues

Summary

Introduction

Freshwater Bryozoa is one of the less explored or ignored animal groups from India. The present study depicts four Phylactolaemata bryozoans species as Rumarcanella vorstmani, Plumatella casmiana, Lophopodella carteri and Swarupella divina. The manuscript provides brief descriptions of these species, photomicrographs of statoblasts using scanning electron microscopy and colony characteristics. Within the phylum Bryozoa, class Phylactolaemata live exclusively in freshwater habitats. Colony morphology and statoblast morphology are used for the identification. Scanning electron microscopy (SEM) photographs are used to describe the surface feature of statoblasts (Wood & Lore 2005). Genus Swarupella was established in India (Shrivastava 1981). The available literature indicates that the studies are restricted to central India.
