A newborn gorilla has died at Bristol Zoo.
Eight-year-old Kala, who arrived at the zoo last year, gave birth by emergency Caesarean last week.
The baby female had difficulties feeding and couldn't be saved, despite the best efforts of keepers and vets.
Staff say the loss is hugely sad and they are working to make sure the young mother recovers.
“This is an extremely sad time for everyone at the Zoo”, said Lynsey Bugg, curator of mammals at Bristol Zoo Gardens.
Western Lowland Gorillas are a critically endangered species.
Bristol Zoo has been caring for gorillas since 1930.
The Zoo plays a significant role in the coordinated European Endangered Species Breeding Programme, runs a conservation programme in Equatorial Guinea in Africa, raises significant funds for gorilla conservation in the wild and has pioneered fertility treatment for gorillas.
