Ctenophora have a one track digestive system that has one opening where food is gathered. They mostly use diffusion as their means of circulating materials through their bodies. digestive systems. Ctenophora are carnivores that use nematocysts to puncture, jab, stick to and/or entrap prey. All there food is passed through a Gastroascular cavity.
