Emus were formerly subject to regulation in the United Kingdom under the Dangerous Wild Animals Act; however, a review of the act in 2007 led to changes that allow emus (alongside a number of other animals that were also regulated under the act) to be kept without a license, as they were no longer considered to be dangerous.
The following species and subspecies are recognized: Dromaius novaehollandiae, emu, remains common in most of the more lightly settled parts of mainland Australia.Overall population varies from decade to decade according to rainfall; as low as 200,000 and as high as 1,000,000, but a typical figure is about half a million individuals.
Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so. Chionophiles are any organisms ( animals , plants , fungi , etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning " snow ", and -phile meaning "lover").

The emus in Van Diemen's Land probably needed fertile and sheltered lands for reproduction on a scale that would maintain their population. The process of farmers taking over, clearing and enclosing stretches of land could have had a detrimental impact on emu populations by limiting the amount of land available for the emu to flourish.
The Kangaroo Island emu or dwarf emu [2] (Dromaius novaehollandiae baudinianus) is an extinct subspecies of emu.It was restricted to Kangaroo Island, South Australia, which was known as Ile Decrés by the members of the Baudin expedition.
A human being can survive an average of three to five days without water. Since the human body is composed of an average of 60% water, it should be no surprise that water is higher on the list than food. [5] [6] The need for water dictates that unnecessary water loss by perspiration should be avoided in survival
