What kind of symmetry does gastropoda have?
Some well known gastropods, which are mollusks, are snails and slugs, and they exhibit what is known as BILATERAL SYMMETRY. The only other kind of symmetry that exists in the animal kingdom, with the exception of colonial species such as the sponge, is RADIAL SYMMETRY. This second type is exhibited by starfish, for example. Cephalopods, another type of mollusk, may appear to be radially symmetric, but are actually bilaterally symmetric due to the composition of their cephalic (head) region.
Asked in Invertebrates
What invertebrate group does the eathworm belong in?
Earthworms belong to the phylum Annelida (ringworms). Note that these are not the only kind of worms; two other phyla are Platyhelminthes (flatworms) and Nematoda (roundworms), and they're all very different from each other. For comparison, another phylum-phylum difference is that between either of the worms and Chordata, being all vertebrates!
