What is another word for casuarius?
Pronunciation: [kˌaʒuːˈe͡əɹɪəs] (IPA) 
"Casuarius" is a word that has a limited range of synonyms, as it refers specifically to the genus of large flightless birds known as cassowaries. However, there are a few alternative terms that could be used in a more general sense when referring to similar birds. A "ratite" is any bird belonging to the group of flightless birds that includes cassowaries as well as ostriches, kiwis, emus, and rheas. A "struthioniform" is a term that encompasses all ratites and is derived from the Latin word for ostrich, Struthio. Alternatively, the term "apteryx" specifically refers to the kiwi, which is also a flightless bird.
