an asymmetrical body plan
Most sponges of the Demospongiae type are considered asymetrical. (Not having symmetry.)
Sponges exhibit a type of symmetry known as asymmetry. Unlike many other animals, sponges do not have a defined shape or symmetry, as they can vary greatly in form and structure. Some sponges may exhibit a degree of radial symmetry, but overall, they lack the organized symmetry seen in more complex organisms.
Sponges are asymmetrical, although a few species have nearly radial symmetry.
Phylum Porifera sponges have radial symmetry.
sponges have no symmetry animals with radial symmetry are radiata and cnidaria, like jellyfish
Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.
Sponges really don't have any kind of symmetry.
Sponges really don't have any kind of symmetry.
Sponges exhibit asymmetry, meaning they lack any distinct symmetry. In contrast, organisms from phylum Cnidaria and Arthropoda typically exhibit radial symmetry (such as jellyfish) or bilateral symmetry (like butterflies), respectively, where body parts are arranged around a central axis or mirror images are present on either side of the body.
Sponges
A finger sponge typically exhibits radial symmetry, with multiple arms radiating outward from a central point. This symmetry allows the sponge to efficiently capture food particles from various directions in its aquatic environment.
Sponges mostly have no symmetry, but it is possible to have a sponge that exhibits radial symmetry. They never have bilateral symmetry.
