Seahorses and seadragons are known for the important and unusual role the males play in incubating and giving birth to the young.
The male incubates the eggs on the underside of the tail (for seadragons) or in a brood pouch (for seahorses). In a matter of weeks, the male releases the young as they hatch. Seadragons can produce up to 500 young at a time, and seahorses can produce up to 900. Seahorses form pairs that last the duration of the breeding season.
