Scientists have cloned an extinct amphibian species that gives birth from its mouth

Australian scientists have produced cloned embryos of the gastric-brooding frog, which was known for giving birth through its mouth.

  • This extinct animal swallowed its eggs, brooded the young in its stomach, and gave birth through its mouth.
  • Even though the gastric-brooding frog became extinct in 1985, a team of researchers was able to recover cell nuclei from frozen frog tissue collected in the 1970s and implant it into a fresh egg from another frog species.
  • Some of the eggs then developed into an early embryo stage, but unfortunately none of the implanted eggs survived longer than a few days.
  • Even though the process has not yet worked, scientists are confident that the hurdles ahead are technological and not biological and eventually the cloning of this species will succeed.
  • Scientists would also like to use this technology as a conservation tool when hundreds of the world’s amphibian species are in major decline.
  • They are also interested in the gastric-brooding frog’s ability to shut down the secretion of digestive acids because it might help develop treatments for gastric ulcers in humans.
