Adelaide Zoo is Australia's second oldest zoo, located in Adelaide, South Australia and the only major metropolitan zoo in Australia to be owned and operated on a non-profit basis. The zoo also owns the Monarto open plains zoo near Murray Bridge. The zoo houses some almost 300 native and exotic species, with over 3,400 animals on site. Currently, two young gorillas can also be seen here on loan from Taronga Zoo, until being sent overseas for breeding.
