Believe it or not Mollusks start out with bilateral symmetry. Some retain it such as slugs, snails, squid, octopuses, and limpets. Then there are others that lose it as they mature such as oysters, clams, scallops, etc.
bilateral symmetry
A snail doesn't really have any lines of symmetry because its shell never rests directly on its dorsal side. If that were the case, the snail would have bilateral symmetry
Mollusks have modified bilateral symmetry. They may be modified from evolving around the phylum, Echinodermata.
I believe that the common mussel has quite a radial symmetry. But don't quote me, I only have my masters in Quantum Physics
bilateral symmetry
yes.
neither, a mussel is a bivalve, which is a type of mollusk, and all mollusks are invertibrates.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
it is not a type of mussel. a niche is a unique way that the animal uses resources in its habitat to make a living. it is not a type of mussel. a niche is a unique way that the animal uses resources in its habitat to make a living.
