Sponges are asymmetrical. Organisms in Cnidaria have radial symmetry while organisms in Arthropoda exhibit bilateral symmetry.

radial symmetry
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral symmetry or "spherical symmetry". A small minority exhibit no symmetry (are asymmetric).
Symmetry in animals is something that is very important. It is a big part of classification in animals. Nearly all multi-cellular organisms exhibit one or other type of symmetry such as radial or bilateral. For more on this see the source.
Earthworms, like all arthropods, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
The phylum Echinodermata has radial symmetry as adults. These organisms include sea stars, sea urchins, and sand dollars, among others. Radial symmetry means that body parts are arranged around a central axis, like the spokes of a wheel.
Porifera and Cnidaria
No, anything in phylum Cnidaria (including corals) have radial symmetry
Animals in the phyla Cnidaria and Echidnodermata (for example starfish and jellyfish) have radial symmetry.
A jellyfish has radial symmetry. A jellyfish is part of the cnidaria species of animals and they generally have radial symmetry. Radial symmetric organisms are like a pie in terms of their shape. THey have no left or right sides. If you were to turn a radial symmetric animal on its side, it would like the same as it did prior.
The most prominent animal phyla with radial symmetry are the Echinodermata (starfish and sea urchins) and the Cnidaria (jellyfish and corals).
sponges have no symmetry animals with radial symmetry are radiata and cnidaria, like jellyfish
Radial symmetry.other animals (exept sponges) and other exeption have bilateral symetry. bilateral symmetrical animals have up and down side, and a front and a back leaving left and right the same. radial animals only have an up side and down side, they do not have a fornt and back side.radial symmetry
The two animal phyla that show radial symmetry are Cnidaria (such as jellyfish and sea anemones) and Echinodermata (such as starfish and sea urchins). Radial symmetry means that the body parts are arranged symmetrically around a central axis, like spokes on a wheel.
Asymmetrical are organisms, such as sponges, that have no true symmetry.
Corals belong to the Phylum Cnidaria. Other animals that belong to the Phylum Cnidaria include jellyfish, hydrae, and sea anemones. Cnidaria are invertebrates (they do not have a backbone) and all have specialized cells called nematocysts that help them capture prey and defend themselves. Cnidaria exhibit radial symmetry.
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.
