MONTEVIDEO, URUGUAY (CNN) – Photos of the sheep in the dark (showing phosphorescent); photo of the sheep with scientists when they were around 30 days-old.

Scientists in Uruguay announced Wednesday the birth of the first genetically-modified phosphorescent sheep.

Nine sheep were born in October 2012 at Uruguay’s Institute of Animal Reproduction, in an experiment done in partnership with the Institut Pasteur.

According to the scientists, the sheep developed normally, without showing any difference with their non-modified counterparts.

Uruguayan scientists used a gene from a jellyfish which is responsible for production of a green fluorescent protein.
