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.
radial symmetry
A slice of lemon displays radial symmetry. This type of symmetry is typically seen in jellyfish and sea anemones.
balls
Bilateral symmetry. This means that the animal's body can be divided into two equal halves along a single plane.
This type of symmetry is called bilateral symmetry. It means that an animal's body can be divided into two equal halves along a single plane, typically the midline, resulting in mirror images.
"bilateral"
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
you can tell if an animal have bilateral symmetry if you cut the animal in half, (hypothetically) and both sides are the same
If a animal has a head then its body symmetry is bilateral.
How can you identify the body symmetry of an animal
An animal whose body can only be divided in one plane to show mirror images is said to exhibit bilateral symmetry. Bilateral symmetry means that the animal has a distinct front and back, a top and bottom, and two sides that are mirror images of each other. This type of symmetry is characteristic of most animals, including humans, and allows for the development of specialized appendages, such as arms and legs, which are important for movement and manipulation of the environment.
If an animal has a head, it is likely to exhibit bilateral symmetry. This type of symmetry means that the body can be divided into two mirror-image halves along a single plane, typically with a distinct front (head) and back (tail). Many animals with heads, such as mammals, birds, and reptiles, have evolved this symmetry as it allows for more efficient movement and streamlined body structures.
