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.
A pregnant Southern platyfish. Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after the egg-sperm union. [1] Although the term often refers to placental mammals, it has also been used in the titles of many international, peer-reviewed, scientific articles on fish.
The female deposits her eggs into the male's brood pouch. Through the pregnancy the pair strengthens their pair bonds with daily greetings. [7] The gestation period for H. barbouri is 12–14 days, with a typical brood size of about 10–240 offspring. They give no parental care to juveniles after birth.
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 ...
The juveniles are approximately 11 mm at birth. They quickly begin to learn and mimic the behavior of its parent. Courtship between the male and female parents begins immediately after birth. The habitat of the lined seahorse is diminishing due to coastal growth and pollution, which ultimately is the cause of the decreasing population.
Ovoviviparity can be thought of as a form of oviparity where the zygotes are retained in the female's body or in the male's body, but there are no trophic interactions between zygote and parents. This is found in Anguis fragilis. In seahorses, zygotes remain in the male's ventral "marsupium".
As many as 250 babies can be released during the delivery.
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 ().
