The young are then released into the water ...
Female, male and juvenile big-bellied seahorses make "click" sounds while feeding, often paired with a head movement called a "snick". Females click more frequently than males, suggesting a possible link to sexual selection.

[4] The most fundamental difference between the different lineages of the family Syngnathidae is the location of male brood pouch. [5]
