Dromaius novaehollandiae, the only member of the family Dromaiidae
- ‘Ostriches, emus, cassowaries, rheas, kiwis, moas and elephant birds really are more closely related to each other than they are to any other birds.’
- ‘Living relatives of moa include the emus, ostrich, and kiwi, which are members of a bird group called ratites.’
- ‘Ostriches and emus are primitive birds that have more in common with dinosaurs than more advanced birds like robins, Schweitzer said.’
- ‘However, the really close resemblance is between ostrich and emu.’
- ‘And the chicks follow the father emu across the highway.’
Early 17th century from Portuguese ema. The word originally denoted the cassowary, later the greater rhea; current usage dates from the early 19th century.
