"It is the male seahorse that is responsible for gestation and birth," Hann told NBC4. "The male seahorse carries fertilized eggs in a pouch and fry are expelled from this pouch a birth." The zoo noted that since seahorses are born small, they will need to mature before they can be viewed by guests. Last August, the zoo revealed that a pair of weedy seadragons, which are seahorse relatives, successfully hatched 26 offspring. "The baby weedy sea dragons ... have been moved to a behind-the-scenes habitat as we prepare for breeding season for the adult weedy seadragons," said Hann. "The adult weedy seadragons are viewable in the Australia and the Islands region. Breeding season for weedy seadragons is dependent on light cycle and water temperature." ...read more read less
