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.
Seahorses should be kept in an aquarium with low flow and placid tank mates. They are slow feeders, so fast, aggressive feeders will leave them without food. [53] Seahorses can coexist with many species of shrimp and other bottom-feeding creatures. Gobies also make good tank-mates.
During intercourse, the female sprays her eggs into the males pouch, which is called a "brood pouch", where they are fertilized and sealed. Females clutch size can be equal to or greater than one thousand and the males' brood size can range from 97 to 1,552 eggs. The number of eggs the female produces varies depending on the size of the seahorse.
During the greeting, the pair change colors and dance together for about 6 minutes. Adult dwarf seahorses are iteroparous, meaning that they have multiple reproductive cycles in the course of their lifetime, in this case 2 per month. [5] [6] Dwarf seahorses remate within 4 to 20 hours after the young have been released from the brood pouch.
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 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.
Females can produce eggs faster than males can brood them, and are limited by the size of the male's brood pouch, which cannot carry all the eggs of a female similar to himself in size. [ 9 ] [ 10 ] Male brood time is approximately four to six weeks, during which time the male provides oxygen and nutrients to the developing embryos until they ...
