Great bustard it well camouflaged in open habitats. Immature birds resemble the female. The eastern subspecies ("O. t. dybowskii") is more extensively grey in colour in both sexes, with more extensive barring on the back. The great bustard has long legs, a long neck and a heavy, barrel-chested body. It is fairly typical of the family in its overall shape and habitat preferences. Three other bustard species overlap in range with this species: the Macqueen's ("Chlamydotis macqueenii"), houbara ("Chlamydotis undulata") and little bustards ("Tetrax tetrax"). However, none of these attains the plumage coloration nor approach the body sizes of this species. Thus,
Edwardsiella tarda in routine tests. This led to the description of two novel species from fish viz "Edwardsiella piscicida" (Abayneh et al., 2013) and "Edwardsiella anguillarum" (Shao et al. 2015) that were previously mis-classified as E. tarda. This might have addressed the arguments between the Japanese and American investigators with regard to the difficulty of differentiating isolates from fish and humans by the time and ended up classifying all into same species i.e. "Edwardsiella tarda". "Edwardsiella tarda" is widely distributed throughout the world. It has been found from the water in Japan all the way to the United States. In Japan it
