We are often asked why we don’t have certain types of animals in our collection — polar bears, hippopotamus, gorillas, cobras and platypus to name just a few. There are a number of reasons:
Space
Perth Zoo has a diverse range of animals. While it would be wonderful to have representatives of all the major animal groups in the Zoo, it is physically impossible to accommodate so many animals in a way that is satisfactory for them and for our visitors. Some species require a lot of space which would require other species having their space reduced to accommodate their new, larger neighbour. This kind of change is only approached with the utmost care and consideration.
Climate
Some species are unable to be kept in WA’s climate without multi-million dollar exhibits to fabricate their own natural environment. Animals like Polar Bears and Emperor Penguins, however popular, require exhibits with 24 hour specialist equipment.
Import Regulations
Some species are unable to be imported into Australia due to quarantine and import regulations.
Breeding Programs
Perth Zoo may have several animals from the same species as result of its role in a breeding program. These numbers fluctuate as the young head off for breeding in other Australiasian zoos. With some species (like Southern White Rhinoceros), the chances of breeding success are increased by the presence of a third or fourth animal. A male and female who have never shown any interest in breeding can be stimulated simply by the presence of a third animal.
Social Hierarchies
Some species are most content when functioning in a large group. Meerkat ‘mobs’ are a good example with dozens of animals living together. Other species, like Sumatran Tiger, prefer their solitude. Perth Zoo tries, wherever possible, to keep the species in appropriate groupings.
Specialisation
Zoos often specialise and focus on a particular area of animal management. Perth Zoo has specialised in a breeding-for-release program for some of our most threatened Western Australian wildlife. For this reason, Perth Zoo has a significantly higher number of native animals than many other zoos.
