Regeneration, reproduction and development in different classes of annelids

Both embryogenesis and regeneration/agametic reproduction involve the establishment of body axes, regional localization and tissue differentiation. However, while embryogenesis is initiated by a single large cell, regeneration and agametic reproduction are initiated by numerous small cells acting in concert.
