Tasmania Zoo only have one Javan (Silvery) gibbon. She’s name Cinta and was born 2009 at Mogo Zoo. Tasmania Zoo intend to import a male from the Greensboro Science Centre in the USA in their near future.
That’s correct re. Lara the Mandrill. As an elderly female, it’s best she remains alone in his familiar surrounds then trying to introduce her to unfamiliar individuals or transferring her to Adelaide to be with their troop. She came to Tasmania as a young animal, where she was initially housed with an ageing male.
