The birth of a Shark breeding To an aquarium from Louisiana, in the United States, has caused a wave of emotion. The breeding was born after Have an egg even though apparently There were no male sharks involved. In the aquarium there were only females.
“In an exciting event for Shreveport aquarium. A shark egg hatched. What makes this so unusual is that there were no male sharks present in their habitat,” says the Shreveport Aquarium In a note.
None of the sharks that could have put the egg had had contact with a male For more than three years. Despite the lack of male sharks in the enclosure, there are two possible ways in which the egg could have produced a baby.
A phenomenon called could have occurred parthenogenesisan asexual reproduction form in which the embryo develops from an ovule without fertilization. There could also have produced a delayed fertilization, that is, something that happens long after mating
Kevin Feldheimdirector of the Pritzker Laboratory of Molecular Systematics and Evolution, whose research focuses on the mating system and population biology of sharks, told the CNN chain that parthenogenesis has been observed in several shark species, including the zebra shark and the Bamboo shark of white spots. It is also believed that it has occurred In a kind of line.
The egg was first identified Eight months agoalthough it is possible that it has remained without detecting for one or two more months. Since its discovery, the egg had been closely monitored in the Aquarium Quarantine facilities, until January 3, 2025, the breeding successfully hatched with the help of the team.
To confirm the exact cause of the birth, the breeding equipment will take samples to perform a cariotype to the breeding once it has an adequate size for a blood extraction, probably after a few months. The analysis of DNA It will provide a definitive confirmation of whether the breeding is a product of parthenogenesis or late fertilization.
