Seahorse life-cycle. The male seahorse is equipped with a brood pouch on the ventral, or front-facing, side of the tail. When mating, the female seahorse deposits up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small. The young are then released into the water ...
Seahorses are renowned for mating for life, with the male carrying the eggs. But after following three male pygmies and one female for weeks, Smith discovered that the sex lives of the smaller ...
Pregnant male seahorse. Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes and males producing smaller gametes ().
When mating, the female seahorse deposits up to 1,500 (average of 100 to 1,000) eggs in the male's pouch, located on the ventral abdomen at the base of the tail. Male juveniles develop pouches when they are 5–7 months old. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small.
As many as 250 babies can be released during the delivery.
Short snouted seahorses are considered ovoviviparous meaning that the female deposits eggs into a pouch on the males stomach, called a brood pouch, and the male goes through pregnancy and labour. [9] Sexual maturation occurs during the first reproductive season after birth.
Although females could technically mate with several males, seahorses form strict monogamous pair bonds for an entire season at least, a rare sight in fish species. [9] Female seahorses remain faithful during the pregnancy by returning to the male's territory each day for an early morning greeting.
The most defining characteristic of Syngnathiformes is their reproductive and sexual system, in which syngnathid males become "pregnant" and carry the embryonic fry. The males house the fertilized eggs in an osmo-regulated brood pouch, or (in some species) adhere them to their tail, until the eggs reach maturity.
