Two baby lemurs have been born at Port Lympne Reserve in Kent.
The white-belted ruffed lemurs, one male and one female, were born on July 10.
First-time mum, Ikala, arrived at the zoo last year from Switzerland, is said to be doing well and has been very attentive to the babies.
The females will usually give birth to twins, but can have up to six babies.
The animals are one of the world’s most endangered primates and are classified as Critically Endangered on the IUCN Red List.
Port Lympne’s Animal Director, Simon Jeffery, said: "Every birth we have here at the reserve is a special moment, but these newborns are important in keeping this particular species from becoming extinct.
"Ikala has been extremely protective of the duo, regularly taking them into the outer enclosure during the day to hide them in the long grass. It’s rewarding to see how well she’s taken to motherhood."
