Aquarium staff in Louisiana has left a puzzle by the “Virgin Birth” a miracle in their fish exhibition.
Yuko generates a young shark (Ceyphaloscyllium Ventriosum) in a full tank in Sharifport Aquarium.
The employees said that the female sharks in the tank – one of them or Yuko – had not been in contact with a male for more than three years.
With pregnancy for swollen sharks somewhere between nine and 12 months, this means that the pregnancy must have occurred in another way.
“This position is incredible and shows the elasticity of this type,” said Greg Barric, a living animal secretary at Sharifport Aquarium.
“It really proves that life finds a way.”
Yoko is believed to be the result of generating generation – a rare type of sexual reproduction as the offspring develops from unusual eggs.
This process is very rare in nature, although it is present in some other species, especially Mayflies, Roman Duke, Snake, Boa.

It is not quite clear what leads to some species to this process, or what links the species that have this ability.
The egg was first recognized by Aquarium staff about eight months ago, although it may have been unveiled for a month to two months before that.
Sherveport Aquarium said in a statement on his website, that he was hatched on January 3 and Yuko is now “prosperous.”
Instead of obstetrics, there is also the possibility of Yuko’s mother to delay in fertilization, as fertilization occurs after a long period of mating.
In the wild, some animals postpone the development of their embryos to wait for better conditions for offspring.
But it is not clear that the fertilization delay in Umuko’s fertilization occurred in captivity.
To find out more, employees will soon take genetic tests on Yoko as soon as they are large enough to test the blood, most likely after a few months.
“We are very excited in the coming months to confirm whether this is already a state of obstetrics or if fertilization is delayed,” Barric added.
Sherveport Aquarium said in a statement on his website that the child Yuko (in the photo) is “currently prosperous”.
“The new Swell Swell, nicknamed Yuko’s affection after Chumash to Shark Onyoko, flourishes under the auspices of the two dedicated Singlers,” said Shreveport Aquarium.
The new Swell Swell Yoko is not yet after the famous Japanese conceptual artist but after the original American Chumash of the shark – “ONYOKO”.
Unfortunately, young sharks who were born through such rare reproductive events often face “great challenges” and die younger.
According to The Aquarium, Yoko’s time could be “brief”, but if so, it will remain “an unforgettable legacy.”
‘[She is] He said that contributing to invaluable visions to study the efforts of shark and conservation.
Virgin births like this are rare in nature and families, but there are similar cases.
Last year, a Boa Strait gave birth to a school in Portsmouth 14 children despite the lack of an opportunity to ignite.
Before that, the sting called Charlotte in North Carolina was said to be pregnant due to the formation of the obstetrician, as a tank did not participate with a male.
Charlotte Stingray died last summer due to a rare reproductive disease – although doubts about her pregnancy were revealed.
Some animals are able to multiply by “forming the prosecution” in which the egg is fertilized with cells from the mother instead of mentioning them
Upon threat, the shark swells (Cephaloscylium Ventriosum) Swallate Sewater, which causes his stomach enlarged and extinguishes predators (file image)
Cephaloscylium ventriosum is a type of original shark of coastal waters in the Eastern Pacific.
Its collection extends from the Gulf of Monterrey in California to southern Mexico and also along the coast of Chile.
Its unique ability to enlarge their bodies to twice the normal size using sea water in order to deter predators.
People do not hunt enlarged sharks on food, but sharks are accidentally caught as a friend of the lobster and lobster, gillnets and nets nets.
“Because sharks take from five to 20 years to ripen and have a few young hunting, such fish that threaten the inhabitants of sharks all over the world,” says Monterrey by Aquarium.
What is swollen shark and how do you multiply?
This shark gets his name from an unusual behavior that he will present when threatened by the predator.
Upon threat, swollen shark swallows huge amounts of sea water, which leads to an enlarged stomach and makes it difficult for predators to eat food
The swollen sharks are an egg, which means that its eggs protect and nourish the fetus until it grows into the range and hatching.
Internal fertilization, but much is not known about mating rituals for swollen sharks.
After mating, two green amber eggs are deposited and are often connected, with the help of the mother, on the substrate like rocks and algae, by eggs oceans in the corners of the egg box.
A large yolk, connected to the fetus by the leg of the egg yolk, provides feeding for the fetus during pregnancy, which is average of 9 to 12 months and depends on the temperature of the water.
