they have just one opening

Explanation:

Cnidarias like hydra, jellyfish etc have only one opening in their digestive tract. It is used for both ingestion and egestion. They take in food with the help of the stinging tentacles. They digest the food intracellularly and cough up the undigested particles from the mouth
