Are annelids born adults or do they develop into adults?

Earthworms are hermaphroditic. They contain both male and female reproductive organs in the same body. These animal usually cannot fertilize themselves. Their fertilized eggs develop into trochophore larvae. They develop into a small version of the adult and grow larger without changing form. They eat decaying vegetable matter in the soil.

The three classes of Annelids are: Oligochaeta (earthworms); Polychaeta (sand worms); Hirudinea (leeches). Leeches are parasitic and are used by the medical profession to withdraw blood from humans in certain situations.

B) Haploid Females. This is because the female is basically cloning herself, so that get rid of all the males. To create queen bees, you'll need males to make some more genetically varied offspring so that 1) you won't have confusion between your workers and hers and 2) you have a greater chance of making a better queen with new genes. That leaves us with Diploid and Haploid females. But because there are no introduction of new genes, that means that the female in question would have the same number of genes as a egg (which is haploid to start off with). Thus, that leave us with B.
