The Singapore Zoo has welcomed a lion cub named Simba to its animal kingdom following artificial insemination that officials said Tuesday was a first for the city-state.

It is rare for lions to be conceived through artificial insemination, with the procedure first carried out successfully in 2018—resulting in two cubs in South Africa.

Lion populations in the wild have plummeted more than 40 percent over the past two decades, with about 23,000 to 39,000 mature animals left, according to the International Union for Conservation of Nature.

The Singapore Zoo has a new lion cub named Simba who was conceived via artificial insemination

It lists lions as vulnerable.

Singapore’s new cub, named after the main character in Disney’s “The Lion King”, was conceived with semen from an elderly African lion.

The father Mufasa, who also takes his name from the animated film, was in poor health and did not survive the procedure, the zoo said.

Simba, who was born in October, is being cared for by his mother Kayla and zookeepers, and is “healthy and inquisitive”, officials said.
