Of course,gastropods [eg:-snail] do not show any symmetry
No, all vertebrates display bilateral symmetry.
All vertebrates including humans display bilateral symmetry.
All vertebrates including humans display bilateral symmetry.
Asymmetrical are organisms, such as sponges, that have no true 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.

Bilateral Symmetry
Asymmetry, or the absence of symmetry, most often occurs in sessile organisms or in slow-moving forms such as amebas .
Hydra are symmetrical radially from the top
Sponges
bilateral symmetry
Hydrozoa, a class of the phylum Cnidaria, typically exhibit radial symmetry. This means their body structure is arranged around a central axis, allowing for multiple planes of symmetry. Most hydrozoans, such as the freshwater polyp and the colonial jellyfish, display this symmetry in their body forms, which facilitates their lifestyle as free-swimming or sessile organisms.
