The basic body symmetry of a cnidarian, especially a jellyfish, is radial, meaning that no matter how it is bisected along its central axis, its two halves will be mirror images of one another.
radial symmetry
Cnidarians typically exhibit radial symmetry, meaning they are shaped like a wheel spoke with multiple identical parts radiating out from a central point. This symmetry allows them to respond to stimuli from all directions equally and efficiently capture prey in their aquatic environment.
They're named from there body symmetry

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, meaning that however you cut them in half the two parts will always be the same - round symmetry, if you will, also found in sea urchins and the like. This is not the most common form of symmetry; bilateral symmetry is (left and right are the same).
Radial symmetry is the main one that distinguishes cnidarians from porifera.
