Euplotes： a skillful hunter
A large Euplotes ciliate has characteristic cirri at the front and rear ends of its body. By actively waving the cilia surrounding its mouth, it creates a whirlpool to attract food particles. Several prey are drawn into its mouth and transferred inside, but some manage to get free.
