Belfast Zoological Gardens is celebrating the arrival of white-belted ruffed lemur twins, born in August 2012.
The latest arrivals are the first white-belted ruffed lemurs to be born at Belfast Zoo. Parents, Wakka and Mianta (pictured), arrived in 2009.
White-belted ruffed lemurs are found in Madagascar, the fourth largest island in the world and one of the most threatened ecosystems on the planet.
White-belted ruffed lemurs are facing a high risk of extinction. Belfast Zoo takes part in the European breeding programme for this species.
The latest arrivals are still young and have not yet been named.
