monecious is when it has male and female reproductive organs in the same organism.
Monoecious mollusks possess both male and female reproductive organs within a single individual, allowing them to produce both sperm and eggs. In contrast, dioecious mollusks have distinct male and female individuals, with each sex producing only one type of gamete. This difference in reproductive strategy can influence their mating behaviors and population dynamics. Examples of monoecious mollusks include many species of gastropods, while dioecious examples include certain bivalves and cephalopods.
Yes.
their weirdness
Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
have a trochophore
Annelids exhibit bilateral symmetry.
Trochophore.
yes

yes.. animal kingdom include,mammals,reptiles,vertebrates,mollusks,annelids,invertebrates..etc etc
Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
Cnidarians include jellyfish and corals. Cnidarians are less complex than annelids or mollusks because the latter have gills with many layers of tissue.
