Euglena sanguinea is a species of euglenid of the genus Euglena. It is a single-celled alga that is found in freshwater habitats, and has a cosmopolitan distribution. As the specific epithet sanguinea suggests, it is often coloured red due to the presence of astaxanthin, and the cells can be populous enough to form blooms that colour the water red.
