The zoo is divided into three principal habitats: Tropical America, the Farmyard, and the Plains of Africa. A newer exhibit is devoted to Australia, with the zoo's first saltwater aquarium. A walk-through aviary and underwater viewing areas with polar bears, sea lions, and harbor seals are additional attractions, and there are a museum of natural history and a planetarium. The facility has looked a bit bedraggled of late, but not enough to deter visits.
