The phylum cnidaria have radial symmetry, meaning their body parts are arranged regularly around a central axis. Most are covered with nematocysts structures which serve as defense against predators and appear to be spines from the outside.
Most animals in the Mollusk phylum have bilateral symmetry, where their body can be divided into two equal halves along a single plane. This symmetry allows for more efficient movement and sensory abilities.
Fish belong to the phylum Chordata, which includes all animals with a dorsal nerve cord. Most fish exhibit bilateral symmetry, meaning they can be divided into two equal halves along a single plane.
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
Symmetry in animals of the phylum is typically categorized as radial or bilateral. Radial symmetry is when an organism can be divided into equal halves in multiple planes around a central axis, like a sea anemone. Bilateral symmetry is when an organism can be divided into two equal halves along just one plane, like a human.

The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
The phylum Cnidaria is comprised of animals that are radially symmetrical and have a jellylike material, called mesoglea, between two layers of cells.
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
I assume you mean in animals? The best example is a sponge, in Phylum Porifera.
Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.
Symmetry in animals of the phylum is typically categorized as radial or bilateral. Radial symmetry is when an organism can be divided into equal halves in multiple planes around a central axis, like a sea anemone. Bilateral symmetry is when an organism can be divided into two equal halves along just one plane, like a human.

Cnidarians are members of the phylum Cnidaria. They are a diverse group of animals that includes jellyfish, corals, and sea anemones. Cnidarians are characterized by their radial symmetry, specialized stinging cells called cnidocytes, and a basic body plan with a central mouth surrounded by tentacles.
Phylum Chordata. Animals with backbones are in the Phylum Chordata. This includes humans and other primates.
Actually all Cnidarians have radial symmetry (able to be divided into identical pie-shaped segments) and have stinging cells. The invertebrate with no symmetry is probably a sponge, phylum Porifera.
