Did you know that it’s the male and not the female seahorses that give birth? When a seahorse mother lays eggs, she puts them in the seahorse father’s pouch. The male seahorse carries the eggs in his pouch until they hatch, then releases fully formed miniature seahorses into the water after about 45 days. As little as 5 or as many as 1,500 young can be born. The baby seahorses float together in small groups, clinging to each other using their tails. Seahorses swim forward by using their dorsal fin and move up and down by adjusting the volume of air in a tiny pocket inside their body called the “swim bladder”.
