A cnidarian has an incomplete gut with just one opening. BTW Those who said that "How many openings does cnidaria have?" and "How many opening does an earthworm have" are the same question are idiots. An earthworm in an annelid, or a member of phylum Annelida. Cnidarians are in an entirely different and less developed phylum, that is, phylum Cnidaria. So there. STAY IN SCHOOL!

Why would a gut with openings at both ends be an improvement over one with only a single opening?
A gut with openings at both ends allows for unidirectional flow of food and waste, preventing mixing and maximizing efficiency of digestion. This also allows for specialized regions within the gut to handle different functions more effectively. Additionally, it reduces the risk of predation and infection by enabling faster expulsion of waste.
