Asymmetrical are organisms, such as sponges, that have no true symmetry.
Organisms that are considered to be simple, such as corals, sponges, urchins, many bacteria and protists all lack bilateral symmetry. The symmetry of these animals is one of the ways they are distinguished from each other and classified into groups.
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.
Asymmetry, or the absence of symmetry, most often occurs in sessile organisms or in slow-moving forms such as amebas .
Asymmetry is the lack of 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.
Asymmetry
A grasshopper is bilaterally symmetrical, meaning its body can be divided into two mirror-image halves along a central axis. This symmetry is characteristic of many animals, allowing for streamlined movement and organized body structures. In contrast, radial symmetry is typically found in organisms like jellyfish, while asymmetrical organisms lack any form of symmetry.
Worms are multicellular organisms belonging to the animal kingdom, while sponges are multicellular organisms belonging to the animal phylum Porifera. Worms have bilateral symmetry and a digestive system, while sponges lack symmetry and have a porous body structure supported by spicules or spongin fibers.
Sponges
Sponges belong to the phylum Porifera and exhibit no body symmetry. Their bodies lack definite shape and are composed of specialized cells organized in a loose aggregation. Sponges are the simplest multicellular organisms and showcase a unique form of asymmetry in the animal kingdom.
Of course,gastropods [eg:-snail] do not show any symmetry
