Twin sister lemurs at Bristol Zoo Gardens appeared to synchronise their births last week when they gave birth within just hours of one another.
It is not uncommon for lemurs to be born at similar times - due to the short length of the mating season - but it is very unusual for two to be born within a matter of hours.
Ring-tailed lemurs are an endangered species and the zoo's walk-through exhibit is now home to nine of them in total. Their numbers have sadly declined in the last few decades, and the biggest reason for this is the destruction of their habitats.
The babies are still too small and close to their mothers' chests for keepers to determine the sexes, but the zoo has confirmed that they are doing well and getting stronger.
