They have a mouth/anus and that is it.
The mouth of a cnidarian, such as a jellyfish or sea anemone, opens into a central body cavity called the gastrovascular cavity. This cavity serves both digestive and circulatory functions, as it allows nutrients to be absorbed and distributed throughout the organism's body.
Cnidarians have no gut in their body .The structure which performs function similar to gut is called gastrovascular cavity .
A medusa has a bowl shaped body with stinging cells on the tips of their tentacles. Their mouth is located on the bottom where their tentacles are, and their central cavity is in the middle of their body. A polyp's body is shaped like a vase with stinging cells at the end of their tentacles, and their central cavity in the middle of their body. Their mouth is on the top of their body with their tentacles.
An anemone has a hollow body. It is a type of cnidarian, characterized by a cylindrical shape with a central cavity called the gastrovascular cavity, which aids in digestion and circulation. The body is surrounded by tentacles that contain specialized cells for capturing prey. This structure allows them to be both flexible and effective predators in their aquatic environments.
