Giraffe gave birth to her 18th ( ! ) young : September 11, 2013 Mother Giraffe Sets a World Record at Everland Zoo 1 giraffe A world record has been set at Everland Zoo in South Korea: Jan-soon, a Reticulated Giraffe, gave birth to her 18th calf on September 8, making her the world's most prolific giraffe mother in captivity. After the birth, mother and calf are both healthy and bonding well. Coincidentally, September 8 was also Jan-soon's 27th birthday, a respectable age for a giraffe. The peak lifespan of a giraffe in the wild is about 25 years. Jan-soon gave birth to her first calf at the age of four. As a giraffe's gestation period lasts about 15 months, Jang-soon has been carrying offspring most of her adult life. She has even given birth to twins. 2 giraffe 3 giraffe 4 giraffe Photo credits: Everland Watch a video of the birth: Jang-soon had shared the record of 17 offspring born in a controlled environment with a giraffe at Paris Zoo named Lamba, who died in 2005. Everland plans to have the record certified by the International Species Information System, a group that keeps a global database on zoo animals. Jang-soon belongs to the endangered Reticulated Giraffe subspecies characterized by white-lined polygonal shapes on a brown coat. There are less than 5,000 reticulated giraffes living in the wild, mostly in eastern African nations like Somalia, Ethiopia and Kenya, according to the Giraffe Conservation Foundation.
