Baby Gorilla Delivered in Rare C-Section at the Bristol Zoo

The baby gorilla was delivered after its mother showed signs of pre-eclampsia.

“Having been involved with the care of these gorillas over the years, with some trepidation and excitement, we were invited to the zoo to assess the well-being of Kera, because she was in late pregnancy and showed some signs of being unwell," Cahill said in the release.

Cahill said the "only way to treat" Kera's condition was to deliver the baby, who was showing signs of distress in his uterus.

“Along with having my own children, this is probably one of the biggest achievements of my life and something I will certainly never forget," Cahill said. "I have since been back to visit Kera and the baby gorilla, it was wonderful to see them both doing so well.”

Bristol Zoo veterinarian Rowena Killick called the Feb. 12 procedure a "very challenging operation" that required an emergency resuscitation of the baby gorilla.

"The baby needed some intensive care immediately after birth and it is still very early days, but we are cautiously optimistic and will be keeping a very close eye on both her and Kera,” Killick said.

The female baby gorilla weighed in at 2 pounds and 10 ounces when she was born, the Bristol Zoo said. She is responding well to "skin-on-skin" contact with her mother, who is recovering and being monitored closely by zoo staff.

The baby gorilla is not yet on display to the public, the Bristol Zoo said. She has not yet been named.
