Instead of growing the baby seahorses inside their belly in a uterus, like human mums do, the seahorse dads will carry the babies in a pouch, a bit like a kangaroo's pouch. To produce babies, seahorses have to mate first. Seahorse mating is really beautiful.

Instead of growing the baby seahorses inside their belly in a uterus, like human mums do, the seahorse dads will carry the babies in a pouch, a bit like a kangaroo's pouch. To produce babies, seahorses have to mate first. ... The eggs are fertilised by the sperm, and then start developing into baby seahorses.

Birth. The number of young released by the male seahorse averages 100–1000 for most species, but may be as low as 5 for the smaller species, or as high as 2,500.

Movement. Seahorses are poor swimmers. They rely on their dorsal fin beating at 30-70 times per second to propel it along. Pectoral fins either side of the head help with stability and steering.

Seahorses prefer tall aquariums with a minimum height of about 18”. The general rule for tank size is 20-30 gallons per adult pair of horses. The height of the aquarium should be at least 3-4 times the height of the Seahorse's adult size.

In fact, some species of seahorse can give birth to more than 1,000 babies at once! ... That's right, males sometimes eat their own babies. It's tough being a baby seahorse. Of the hundreds of babies that the male gives birth to, only one or two will survive to become adults and have babies of their own.

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, and the male often mates again within hours or days during the breeding season.

When the tiny seahorses are ready to be born, the male undergoes muscular contractions to expel the young, known as "fry," from the pouch. While seahorse dads go the extra mile to give birth, the parents do not provide their tiny offspring with any care or protection after they are born.

Macro-algae can thrive in an aquarium with minimal care. Seahorses prefer tall aquariums with a minimum height of about 18”. The general rule for tank size is 20-30 gallons per adult pair of horses. The height of the aquarium should be at least 3-4 times the height of the Seahorse's adult size.

But they do outdo human dads on one count: Male seahorses undergo pregnancy and give birth to their sons and daughters. The trait is unique in these strange and fascinating fish that inhabit tropical and temperate coastal waters worldwide.

But, for three animals, the tables are turned. Male seahorses, pipefish, and sea dragons are the ones who get pregnant and give birth to their young. So how do they do it? When it comes to seahorses, males have a pocket on the front of their bodies called the brood pouch.

The Knysna seahorse is not exploited for traditional medicines. However, according to the IUCN's red data book, they are listed as the most endangered seahorse in the world. The reason for this is primarily due to their exceptionally limited distribution range as they are endemic to a few southern Cape estuaries.

But in seahorses, the sperm-producers are also the ones that get pregnant. The female transfers her eggs to the male's abdominal pouch, made of modified skin. The male releases sperm to fertilise the eggs as they enter, before incubating them for 24 days until they are born.

They are usually yellow, orange, pink, or gray changing color to blend in with their surroundings. They have a narrower snout than other seahorses and a prehensile tail to hold onto the fan corals they call home.

Habitat. Seahorses are mainly found in shallow tropical and temperate salt water throughout the world, from about 45°S to 45°N. They live in sheltered areas such as seagrass beds, estuaries, coral reefs, and mangroves. Four species are found in Pacific waters from North America to South America.

In Thoroughbred racing, there are races for female horses (fillies and mares) only. (A female Thoroughbred is a filly until she turns 5, and then she is a mare.) Male horses, including geldings, race against each other, but with few exceptions, their races are also open to females.
