  1. Jellyfishes vs. Earthworms By Nastya Mozolevych

  2. Jellyfishes • They are members of the phylum Cnidaria that are free-swimming. • They reproduce sexually and asexually. • Their embryos develop inside the female or in brood pouches (near the oral arms). • After the young are made, they leave the female. After several days of floating, they attach themselves to something on the sea floor. Then they transform into flower (not really flower, like in ilustration) and start the life cycle over again. • So, after birth parents just let their jellyfish go.

  3. Earthworms • They are segmented animals that are tube-shaped. They live in soil and feeds on live and dead organic matter. • Earthworms reproduce sexually. They have both male and female reproductive organs. During the reproduction both sets of sex organs are used by both worms. Then, fertilization occurs in both of mates eggs. • Their embryo develop outside. • After external fertilization, the slime is left. It develops into a cocoon. Egg remains in the cocoon until the conditions are right for it to survive. After it hatches, it doesn’t reach sexual maturity until two-four years pass. • So, after the young is made, the parents leave it.

  4. Same things in both • After the young is born, both jellyfishes and earthworms leave it.

  5. Different things • Jellyfishes reproduce both sexually are asexually, while earthworms reproduce only sexually. • Jellyfish’s embryo develops inside, while earthworm’s outside. • Their young develop differently.
