About 6-8 weeks after conception, the male releases miniature sea dragons into the ocean by pumping his tail until the young ones emerge – a process which takes place over 24–48 hours. The male aids the hatching of the eggs by shaking his tail, and rubbing it against seaweed and rocks. After the eggs have hatched, each baby sea dragon has a small yolk sack attached externally to it. This sac will provide the new born with food over the next few days.
