This sentence is true in the case of gastric cavity of cnidarians - digestive enzymes released into the gastric cavity allow the consumption of whole prey such as fish.
Extracellular digestion is carried out by cnidarians, in which the cells that line the gastrovascular canal receive the nutrients and enzymes split down the food particles. With only one opening, the gastrovascular cavity that doubles as both the mouth and the anus in cnidarians acts as their only digestive system. There is only one entrance in the central gastro-vascular cavity, which serves as both a mouth and a drain for waste. Digestion occurs both within and outside of cells.
Cnidarians consume food through their lips, and the coelenteron then breaks it down. Waste products are subsequently eliminated either via the mouth or via cell surface via water circulation, while nutrients are then sent to other parts of the body for use.
