How does the digestive system of a hydra compare with that of an earthworm?

The hydra has a single opening digestive tract so what goes in has to come out the same way. Worms have two openings to their digestive tract so things can just go straight through without any stopping. This is an interesting - if rather standard - exam question. Looked at from an evolutionary point of view it is clear that the gut structure present in the earthworm offers far more potential than the hydra's simple 'gutbucket'and has, (unlike the latter) been exploited along the length of the evolutionary path starting from the point after hydra. The questions that follow from this include how did the gut structure evolve, what competitive advantage does it offer and, most important of all, why. Jon P Baker, Sheffield, England

What is an open digestive system?
An open digestive system is one where there is an entrance "mouth" in one end of the organism and an "exit" or anus of some sort in the other end of the organism. (think of worms or people). A closed digestive system is in something like a hydra or anemone where there is just one cavity and one opening that acts as both mouth and anus.

Which organism uses the same opening for ingestion and egestion?
Organisms that have only one opening in their digestive tract through which food enters and waste exits are known as having an incomplete digestive system. Some organisms with incomplete digestive systems are jellyfish, sea anemones, flatworms, and corals.
What is true for both incomplete and complete digestive systems?
An incomplete digestive system (found in certain lower invertebrates like Cnidarinas, i.e. hydra, marine jellyfish, and Platyhelminthes, i.e. flatworms) is where a single opening to a pouch-like cavity serves as both mouth and anus. A complete digestive system (all insects have them) means that food processing occurs within a tube-like enclosure, the alimentary canal, running lengthwise through the body from mouth to anus.
