White abalone reproduce by releasing their eggs and sperm into the surrounding water, known as broadcast spawning. If fertilized, the eggs hatch after only one day, but high concentrations of sperm are required in order for an egg to be fertilized.
Worms have a very interesting method of reproduction. There are no male and female worms â all worms are the same and each produce both sperm cells and egg cells. When a worm is mature and ready to reproduce, it finds a partner worm.They line up head to head attaching themselves together at the clitella (the thick light colored band around each mature worm) and mucous is secreted. The sperm cells are exchanged by the worms through this mucous.hen a worm is mature and ready to reproduce, it finds a partner worm.
