The Life Cycle Of Obelia
Obelia
undergoestwo forms in its life cycle. They are polyph form and medusa form.
Polyph-formed
obelia reproduces asexually by budding. That bud stays attached to the parental
body until it forms a colony. In the colony there are two kinds of the polyph :
those with tentacles and those without any tentacles.poliph lacking tentacles
are for reproduction by forming medusa through budding. Medusa will be released
from the polyph and then matures. Mature medusa produce sperms and ovum. Then they
are released into the water and produces zygotes. Zygotes develop into
cilliated larvae (planula). Planula attaches to sea floor or rocks and grow
into mature Obelia polyph.
After that the
cycle repeats.
