Miraculous birth of a baby shark without a male shark in an aquarium
Barcelona: The birth of a baby shark in a tank containing the female “Smooth Hound Shark” in an Italian aquarium has been called a “miracle” because no male shark was involved.
It should be noted that the birth of offspring without mating in male and female sharks is a very rare occurrence, but before that such incidents have occurred in three species of sharks, namely bonnet head, back tip shark and zebra shark. In scientific parlance this process is called “parthenogenesis”.
The incident took place at the Aquarius Cella Gonon, a fishing village on the famous Italian island of Sardinia.
The newborn baby shark has been dubbed “Spirea” but has become known in Italian and international media as the “miracle shark”.
Aquarium experts have sent blood samples from Asperia and her mother to the laboratory.
If confirmed, it would be the fourth species of shark to observe parthenogenesis.
It should be noted that so far, the role of cells called “polar cells” has been found in female sharks to conceive without mating with males, including a copy of the DNA of the female shark’s egg. ) Exists.
There is a time in years when this same polar cell, in the absence of a male shark, fertilizes the egg and causes the female shark to become pregnant.
The resulting shark is not only a female, but also a genetic photocopy of the shark that gave birth to it. Which is called “clone” in scientific language.
