Yes. Crabs and other crustaceans have bilateral symmetry. Bilateral symmetry means something 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.
Starfish appear radially symmetric, but they are actually classified as bilaterally symmetric organisms. That is actuall wrong...they are radially symmetrical, but they do develop from bilaterally symmetrical larvea
From PattiVan:
Think of the starfish like bicycle wheel and the legs are its spokes. The spokes are placed in a radial fashion from the center leading out; so the starfish has radial symmetry. (They sdo start out in life bilateral however.) Easy to remember this way.
yes :)
Oysters have irregularly sized shells, very different making them asymmetrical, not the usual bilateral symmetry of other bivalve mollusks.
Yes, a crab has bilateral symmetry. All crustaceans have bilateral symmetry.

One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
