Rotifers do not have hearts. Instead of a circulatory system with a heart, they rely on a pseudocoelomic fluid that circulates nutrients and waste throughout their body. This fluid movement is facilitated by the contraction of body muscles and cilia, allowing for the distribution of substances necessary for their survival.
