Bilateral, meaning left and right are equal.
Invertebrates do not have backbones, and include lobsters, snails, and squids. Invertebrates also include the crab, beetle, starfish, and sea cucumbers.
radial symmetry
yes
Sponges are asymmetrical. Organisms in Cnidaria have radial symmetry while organisms in Arthropoda exhibit bilateral symmetry.
Yes. Most phyla evidence bilateral symmetry including flatworms, earthworms, many molluscs, and chordates including fish and mammals. Arthropoda, including insects, are bilaterally symmetric.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
Phylum arthropoda is classified under a taxonomical unit (subregnum) Bilateria, which includes all phyla except the placozoans, cnidarians, ctenophores and sponges (porifera). Bilateria all have bilateral symmetry, or could be reflected in a hypothetical mirror placed down the midline, and includes the crustaceans.
No. 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.
