Euastrum elegans is a species of green algae known as a desmid, characterized by its crescent-shaped cells with a central constriction dividing them into two halves. Each cell has a rigid cellulose cell wall and contains chloroplasts arranged in a star-like pattern. The nucleus is centrally located. This species reproduces both sexually and asexually and is ornamented with spines or ridges, contributing to its symmetrical and decorative appearance. Euastrum elegans inhabits freshwater environments, where it plays a crucial role as a primary producer.
