There are small hepatic papillae on the external side of the stomach. No folds have been detected on the stomach wall. The intestine is wide, it extends in a long primary closed loop, and forms a secondary wide loop. The gaping anus opens with a smooth rim. The base of the rectum is attached to the stomach.
