The emu (/ ˈ iː m juː /; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird. It is the only extant member of the genus Dromaius and the third-tallest living bird after its African ratite relatives, the common ostrich and Somali ostrich. The emu's native ranges cover most of the ...
Some Australian fossils initially believed to be from emus were recognized to represent a distinct genus, Emuarius, [a] which had a cassowary-like skull and femur and an emu-like lower leg and foot. In addition, the first fossils of mihirungs were initially believed to be from giant emus, [ b ] but these birds were completely unrelated.
Emuarius is an extinct genus of casuariiform flightless bird from Australia that lived during the early Miocene and late Oligocene.It is one of two known genera of emu. [3] There are two known species in the genus, Emuarius gidju and Emuarius guljaruba.
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.

These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Trichostrongylus species are nematodes (round worms), which are ubiquitous among herbivores worldwide, including cattle, sheep, donkeys, goats, deer, and rabbits. [1] [2] [3] At least 10 Trichostrongylus species have been associated with human infections. [1]
Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection. There is a naming convention which applies to all helminths: the ending "-asis" (or in veterinary science: "-osis") is added at the end of the name of the worm to denote the ...
