sentence: Brine shrimp take in food though their mouth.
sentences_after: The food then travels through their esophagus to their stomach, which is in the head. Then, the food travels to the intestine, a long tube that runs throughout the body. While in the intestine, food is broken down using enzymes. Blood vessels surround the intestine, and nutrients from the food pass through the intestine walls and are absorbed into the bloodstream. In their natural habitat, brine shrimp generally feed off algae, and other animals, in turn, feed off them.
