Eudorina
Genus of algae
Eudorina is a paraphyletic genus in the volvocine green algae clade.[1] Eudorina colonies consist of 16, 32 or 64 individual cells grouped together. Each individual cell contains flagella which allow the colony to move as a whole when the individual cells beat their flagella together. Description by GM Smith (1920, p 95):[2]
