A feminine stingray in a North Carolina aquarium is pregnant — though there are not any males in her tank.

The mysterious being pregnant has turn out to be the topic of widespread fascination, with many questioning how the spherical stingray, named Charlotte, got here to be pregnant.

“The unique thing about Charlotte is we don’t have a male ray,” Brenda Ramer, government director of the Aquarium & Shark Lab in Hendersonville, stated in a video on Facebook.

Aquarium workers imagine Charlotte’s seemingly immaculate conception is the results of parthenogenesis, a uncommon type of asexual copy noticed in some animals, together with fish, birds, bugs, and amphibians.

Charlotte was discovered lined in shark bites — an indication of mating in sharks — which initially led some to invest {that a} shark was the daddy, and Charlotte’s child can be a shark-stingray hybrid.

But Kady Lyons, a analysis scientist on the Georgia Aquarium, instructed the Associated Press this form of interspecies copulation will not be biologically doable.

“We should set the record straight that there aren’t some shark-ray shenanigans happening here,” Lyons stated.

Even so, Charlotte’s being pregnant is not any much less exceptional — she is the one recognized case of her species to turn out to be pregnant by parthenogenesis, Lyons stated.

“We don’t know why it happens,” Lyons stated. “Just that it’s kind of this really neat phenomenon that they seem to be able to do.”

Charlotte is anticipating three or 4 pups, and is predicted to provide delivery in a couple of week.
