Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that zoos can provide refuge against diseases, competition with others of the same species and predators if animals in there are treated well. Most notably, animals ...
Conservation efforts have grown an initial wild population of 30–40 to over 100. [3] All species of Potorous are well within the "critical weight range" for mammals in Australia, those weighing from 35 to 4,200 grams (0.077 to 9.3 lb; 1.2 to 150 oz) whose trajectory was toward decline or extinction during British settlement.
The oldest known bird in the world was an Australian sulphur-crested cockatoo called Cocky Bennett, who lived to 120. [112] He could recall phrases such as "one feather more and I'll fly" and "one at a time, gentlemen, please". He lived from 1796 to 1916 and traveled the world with various owners.

As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species. The IUCN also lists five animal subspecies as extinct in the wild. This is a complete list of wild animal species and subspecies listed as extinct by the IUCN.
The red kangaroo is the largest extant macropod and is one of Australia's heraldic animals, appearing with the emu on the coat of arms of Australia. [1]The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
The opossum lifespan is unusually short for a mammal of its size, usually only one to two years in the wild and as long as four or more years in captivity. Senescence is rapid. [ 37 ] Opossums are moderately sexually dimorphic with males usually being larger, heavier, and having larger canines than females. [ 36 ]
