Once common on the east coast of Australia, emus are now uncommon there; by contrast, the development of agriculture and the provision of water for stock in the interior of the continent have increased the range of the emu in arid regions. Emus live in various habitats across Australia both inland and near the coast.
Emus are soft-feathered, brown, flightless birds with long necks and legs, and can reach up to 1.9 metres (6.2 ft) in height. Emus can travel great distances, and when necessary can sprint at 48 kilometres per hour (30 mph); they forage for a variety of plants and insects, but have been known to go for weeks without eating.
Two large emus on the loose in South Carolina ruffled the feathers of locals a week after dozens of monkeys escaped from a research facility in the Palmetto State.
Many of the larger ratite birds have extremely long legs and the largest living bird, the ostrich, can run at speeds over 35 mph (60 km/h). Emus have long, strong legs and can run up to 30 mph (48 km/h). Cassowaries and rheas show a similar likeness in agility and some extinct forms may have reached speeds of 45 mph (75 km/h).

Reports of two large emus running riot in the city of Loris, in Horry County, SC, followed an incident last week when 43 monkeys escaped an Alpha Genesis facility in Beaufort County, SC, the ...
However, they will eat insects if the opportunity arises. Emus have tracts of 7 m (23 ft) length, and have a more omnivorous diet, including insects and other small animals. Cassowaries have next to the shortest tracts at 4 m (13 ft). Finally, kiwi have the shortest tracts and eat earthworms, insects, and other similar creatures. [39]
There are over 60 extant species, [2] including the well-known ratites (ostriches, emus, cassowaries, rheas, and kiwis) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7 g).
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.
