Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | Eggs | Fecundity | Larvae
Members of the order Doliolida includes clonal and sexual phases in its life cycle. Life cycle: The doliolid nurse (oozoid, a colony of polymorphic zooids) develops from a fertilized egg and subsequent tadpole larva. The colony arose by budding from the oozoid's stolon, each buds migrate and lodge to the oozoid's spur where they began developing into trophozooids (feed the phorozooids). Buds attached to the phorozooids develop into sexually reproductive gonozooids.
