Cnidarians have a radial symmetry.
Cnidarians have radial symmetry and specialized stinging cells called cnidocytes, while mollusks typically have bilateral symmetry and a muscular foot for movement.
Cnidarians are a phylum of invertebrate animals that includes jellyfish, corals, and sea anemones. They are characterized by their radial symmetry and specialized stinging cells called cnidocytes, which they use to capture prey. Cnidarians are found in marine environments around the world.
Sponges are invertebrate animals that usually have no body symmetry and never have tissues or organs. Cnidarians use stinging cells to capture food and defend themselves. Flatworms are flat and as soft as jelly. Unlike cnidarians or flatworms, roundworms have a digestive system that is like a tube, open at both ends. Earthworms and other segmented worms have bodies made up of many linked sections called segments.
All cnidarians have on their tentacles stinging cells called nematocytes. They have no brains or a central nervous system. Another common feature is that they all can regenerate, letting them produce asexually (without the need for another partner) and to recover from injury.

Cnidarians
Some have asymmetry, but most have radial symmetry.
Radial symmetry
Cubazoa are a group of cnidarians. Cnidarians are animals that have radial symmetry and are usually venomous or poisonous.
Cnidarians exhibit radial symmetry, which means their body parts radiate out from a central point. This symmetry allows cnidarians to capture prey efficiently from all directions.
Radial symmetry is the main one that distinguishes cnidarians from porifera.
Cnidarians and echinoderms
Cnidarians belong to the Kingdom Animalia. They are characterized by their radial symmetry, tentacles with stinging cells called cnidocytes, and a simple nerve net.
