How to identify Eudorina
- Under the microscope: ball shaped colony of 16 to 64 round green cells spaced inside clear jelly
- Each cell has two flagella and the whole colony rolls through the water
- In the water: blooms make the water bright green

Pandorina cells are packed tightly together; Volvox colonies are much larger with hundreds to thousands of cells.
