Chicago Shedd Aquarium and Field Museum researchers have published a news study after zebra shark Bubbles gave birth through parthenogenesis.
The Shedd Aquarium's female zebra shark Bubbles recently gave birth to twins through parthenogenesis, somtimes called "virgin birth." She fertilized her own eggs herself.At six and a half feet long zebra sharks are one of the largest species at Chicago's Shedd Aquarium. The endangered animals, which are native to Indonesia, have been a fixture at the Wild Reef exhibit since it opened almost 20 years ago.
The pups were all conceived with the help of male sharks, or so they thought, until genetic testing was done on the offspring of a zebra shark named Bubbles. She is the first known at the Shedd to reproduce by a process called parthenogenesis, meaning "virgin birth," in which Bubbles fertilized an egg with her own genetic material.
While zebra sharks are a species that can reproduce asexually, it is rare. Reserachs said it's even more unusual that Bubbles chose parthenogenesis even though she was exposed to three mature breeding males. Feldheim said the question must be answered for the survival of zebra sharks. He said virgin birth pups have low rates of survival; the two born to Bubbles both died.
