The video was shared by USA's The Smithsonian's National Zoo & Conservation Biology Institute on their official Twitter handle.

Calaya, a 15-year-old western lowland gorilla who lives at Washington DC's National Zoo, gave birth to her first offspring, a male named Moke, which means "junior" or "little one" in the Lingala language of Africa. Members of the zoo staff said it was an amazing event.

The cheetah cub looked supremely irritated as the animal biologist put it down on a soft black cloth to have its portrait taken.

Cuteness overload, times two -- Mei Xiang, a giant panda at the Smithsonian's National Zoo and Conservation Biology Institute, gave birth to twin cubs on August 22. Both cubs, the first born at 5:35 pm and the second at 10:07 pm, are healthy and doing well.
