bilateral symmetry
Molluscs exhibit bilateral symmetry, meaning their body can be divided into two mirror-image halves along a single plane. This symmetry is evident in their body structure, which typically includes a distinct head, a muscular foot, and a visceral mass containing most of their internal organs. Some molluscs, particularly certain bivalves, may show variations in symmetry due to their lifestyle and habitat.
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection

Asymmetry, Radial Symmetry, and Bilateral symmetry.
bilateral symmetry
Some mollusks have bilateral symmetry. Mollusks include gastropods such as snails, bivalves such as oysters, and cephalopods such as squid. Some bivalves have bilateral symmetry.
nope. Some bivalves have bilateral symmetry but no radial symmetry.
Mollusks are defined as Bivalves. They are called Bivalves because they have two shells. Cnidarians such as Jelly Fish do not have shells which define a bivalve (mollusks).
The oyster is less bilaterally symmetrical when compared to other bivalves. The right side is less developed than the left.
Bivalvia is the scientific name for the bivalves.

Many think that the limpet has radial symmetry but this is not the case. Limpets have bilateral symmetry. Bilateral symmetry means the animal has 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.

It has two valves, hence bi....

Bilateral symmetry is not typically an adaptation of most sessile organisms; rather, many sessile organisms exhibit radial symmetry. Radial symmetry allows them to efficiently interact with their environment from all directions, which is advantageous for feeding and reproduction. However, some sessile organisms, like certain bivalves or barnacles, may exhibit bilateral symmetry during their larval stages. Overall, the symmetry seen in sessile organisms is primarily a reflection of their ecological niches and lifestyle rather than a strict adaptation.
All mollusks exhibit bilateral symmetry, meaning their body can be divided into two mirror-image halves along one plane. While some mollusks, such as bivalves, have hinged shells, this trait is not universal among all mollusks. Radial symmetry and the ability to swim are also not characteristics found in all mollusks. Thus, bilateral symmetry is the defining feature present in all members of this diverse phylum.
