It sounds crazy, but it is true. Seahorses and their close relatives the pipefish and the seadragons are very unusual, because it is the males that get pregnant and give birth to the babies. ... The females then put their bright orange eggs into the pouch of the males through the hole at the top of the pouch.

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.

Using muscular contractions of the brood pouch, the male will birth the young seahorses. Depending on the species, males can give birth from 5 to 2,500 young. Crepidula is a sequential hermaphrodite. During the same course of life, this limpet will change sex from male to female.

In asexual reproduction, an individual can reproduce without involvement with another individual of that species. ... Sexual reproduction in seahorses: Female seahorses produce eggs for reproduction that are then fertilized by the male. Unlike almost all other animals, the male seahorse then gestates the young until birth.

They are fish, but they have a horse-like head, a monkey-like tail and a kangaroo-like pouch. They have a few things in common with chameleons as well - they can move their eyes around, and change their skin colour! Seahorses can even grow bits of skin that look like seaweed to help them hide better.

Seahorses are not cheap. The average is about $100.00 for 10 dwarf horses. This is why you need to do your research to ensure that they will live before spending any money. They also require a lot of care.

Seahorse oraganelles, called chromatophores, are embedded within their skins. These tiny, sacklike organs contain a number of pigments and can expand or contract in response to a variety of stimuli, causing the seahorse to change color.

Seahorses belong to the genus Hippocampus, while their close relatives, the two species of sea dragons, belong to the genera Phycodurus and Phyllopteryx. The sea dragons are endemic to Australian waters, while seahorses roam mostly tropical and subtropical waters around different areas of the world.

Because they swim so slowly, eating can be a challenge for the seahorse. Further complicating things is the fact that a seahorse has no stomach. It needs to eat almost constantly because food quickly passes straight through its digestive system. ... Seahorses do not have teeth; they suck in their food and swallow it whole.

Researchers at the University of Sydney observed a three-toed skink lay three eggs and weeks later give birth to a live baby. “This is the first time that anyone has observed live birth and egg laying in a single litter in a vertebrate animal and it's very, very unusual,” research author Camilla Whittington said.

Male Contractions A pregnancy lasts from 10 to 25 days, depending on the species. The reproductive process begins when a male and a female seahorse do daily pre-dawn dances, intertwining their tails and swimming together. Eventually they engage in a true courtship dance, which can last as long as eight hours.

Seahorses are bony fish but they lack the corresponding scales. Instead, their skin is stretched over bony plates, giving the appearance of an exo-skeleton. A prehensile tail allows seahorses to cling to vegetation preventing them from being washed away in the current.

Spines and Appendages While the seahorses' bony plates create stiff spines along parts of the body, the sea dragons have leaflike appendages. The leafy sea dragon (Phycodurus eques) is much more elaborate, with loose, flowing appendages that look much like floating pieces of seaweed or other plant material.

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.

The female usually lays the eggs, and the embryos in the eggs develop and hatch outside her body. These kind of fish are called 'oviparous' fish. ... The young of viviparous species of fish are also 'born alive'. Livebearers is a term used to describe fish who give birth to live young.
