Pygmy hippos are primarily threatened by loss of habitat, as forests are logged and converted to farm land, and are also vulnerable to poaching, hunting for bushmeat, natural predators, and war.

The plural form is pygmy hippopotami ("hippopotamuses" is also accepted as a plural form by the OED, or "pygmy hippos" for short). A male pygmy hippopotamus is known as a "bull", a female as

Climate change is another serious threat to the mountain pygmy possum. "Burramys parvus" is the only Australian mammal which is completely restricted to the alpine regions. The species is well adapted to the seasonal availability of Bogong moths and other food resources. Although data from New South Wales and Victoria are still pending, preliminary models suggest that reduced survival of mountain pygmy possums can be related to declining snow cover and shorter winters. Studies conducted at Kosciuszko National Park revealed that the period of snow
