How long is the pregnancy and how big are the young?
Pregnancy lasts about two weeks to one month, the length decreasing with increasing temperature. At the end of gestation the male goes into labour (usually at night), pumping and thrusting for hours to release his brood. Young are miniature adult seahorses, independent from birth, and receive no further parental care. Newborns of most species measure between 7 and 12 mm. Most males give birth to around 100-200 babies, however the smaller species can have a few as give, and one Hippocampus reidi male gave birth to 1572 young!
