Quizplus · Accepted Answer

Moving onto land for fertilization is not a strategy used by aquatic animals to increase the success of external fertilization. This strategy would actually hinder fertilization as it would prevent the gametes from coming into contact with each other in the water. Elaborate courtship rituals, production of a large number of gametes, and release of pheromones are all used by aquatic animals to increase the chance of successful fertilization.
