Casuariiformes Casuariiformes The Casuariiformes is an order of large flightless bird that has four surviving members: the three species of cassowary, and the only remaining species of emu. They are divided into either a single family, Casuariidae, or more typically two, with the emu splitting off into its own family, Dromaiidae. All four living members are native to Australia-New Guinea, but some possible extinct taxa occurred in other landmasses. The emus form a distinct family, characterized by legs adapted for running. As with all ratites, there are several contested theories concerning their evolution and relationships. As regards this order, it is
Emu oil other as an insect repellent. Emu oil Emu oil is an oil derived from adipose tissue harvested from certain subspecies of the emu, "Dromaius novaehollandiae", a flightless bird indigenous to Australia. Unadulterated emu oil can vary widely in color and viscosity anywhere from an off-white creamy texture to a thin yellow liquid, depending on the diet of the emu and the refining method(s) used. Industrially refined "emu grade" emu oil is composed of a minimum of 70% unsaturated fatty acids. The largest component is oleic acid, a monounsaturated omega-9 fatty acid. Emu oil also contains roughly 20% linoleic acid (an
