Nitzschia flexa is a pennate diatom (class Bacillariophyceae) with a characteristically curved or bent raphe system that gives the genus its distinctive appearance. It inhabits freshwater to brackish environments and contributes to benthic and planktonic algal communities. As a photosynthetic microalga, it plays a foundational role in aquatic food webs and primary production.
