Oceania (sometimes Oceanica) is a geographical, and often geopolitical, region consisting of numerous lands—mostly islands in the Pacific Ocean and vicinity. The term "Oceania" was coined in 1831 by French explorer Dumont d'Urville. The term is also sometimes used to denote a continent comprising Australia and proximate Pacific islands, and is one of eight terrestrial ecozones.
The boundaries of Oceania are defined in a number of ways. Most definitions include Australia, New Zealand and all or part of the Malay Archipelago. Ethnologically , the islands that are included in Oceania are divided into the subregions of Melanesia, Micronesia and Polynesia.
Aprox 39 million people can call Oceania theire home. I only found bigger Aquarias and Zoos in Australia(27), New Caledonia (1) and New Zealand (2), making it a total of 30. All three countries have a lot of endemic species, wich are rarely seen in the zoos out side of the region (except some species of kangaroos, cockatoos and the emu). So combining a zoo ore an aquarium trip with a trip to the local nature is always the money worth. Sadly though is New Caledonia is of the beaten track, so getting there can sometimes be a problem.
Out of the 30 Aquarias and Zoos only 11 have 200 species ore more, and thereby being a big institution. All of these are in Australia, the biggest Aquarium is in Sydneye and the biggest Zoo is in Mosman.
