Abstract - This study focuses on the morphological characteristics of diatoms found in Chennai's numerous bodies of water, including rivers, lakes, and coastal waters. they are one of the most abundant single-celled photosynthetic algae, contributing to about 40% of total marine primary production. diatoms are important primary producers and bioindicators of water quality because of their unique silica-based architecture. By analysing the diverse shapes of diatoms, this study aims to understand how their morphology differs in different aquatic environments. In this review, we first introduced the role of diatoms in forensic evidence and it might help clarify how diatoms are used in forensics, to determine the time and location of death in drowning cases. The study finally advances our understanding of diatom ecology and its role in Chennai's aquatic ecosystems.
