Two month-old twin ring-tailed lemurs get a lift from their mum around their enclosure at Marwell Zoo near Winchester where staff have managed to produce five young this year from three females; Claire, Glenys, and Martini. * Keepers at the zoo have been trying to breed the primates since 1996 when a new male called Genou was brought from Zurich Zoo in Switzerland. They are officially a vulnerable species due to destruction of their habitat in their native Madagascar. Stock Photo
