A Simple Method for Scanning Electron Microscopy (SEM) Study of Cla

Scanning Electron Microscopic (SEM) study requires an expensive, complicated and timeconsuming method for sample preparation of aquatic invertebrates. In this paper a simplified sample preparation technique without dehydration, critical point dry, for SEM study of Bosmina tripurae was proposed. The present investigation included detail morphology of different life history stages of this cladocera,, especially ephippium structure, surface sculpture, postabdominal claws of adult male and parthenogenetic female and spines of posterior margin, carapace of juvenile female and adult male, antennules and mucro of juvenile female, for further confirmation of its taxonomic identity. From this SEM study it was concluded that Bosmina tripurae is under the subgeneric group Bosmina, not the Sinobosmina.
