Tulodens are 2 of the slow-moving form of protozoa. They move around with whip-like tails called flagella, hair-like structures called cilia, or foot-like structures called pseudopodia. Others do not move at all. Protozoa may absorb food via their cell membranes, some, e.g., amoebas, surround food and engulf it, and yet others have openings or "mouth pores" into which they sweep food,and that engulfing of food is said to be phagocytosis. All protozoa digest their food in stomach-like compartments called vacuoles.
