👉 Euglena is a type of algae that lives in water bodies, primarily freshwater systems, but also in seawater and some marine environments. Its cells are very small, with a spherical shape, and it has a high surface area-to-volume ratio, enabling it to grow rapidly. Euglenae are known for their ability to survive in low light conditions, as well as their ability to form symbiotic relationships with certain microorganisms.
