U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Marinka: Sharka cad ee badweynta, ama shark cad oo yar, waxaa sharraxay 1831 kii dabiiciga ahaa ee René-Primevère Lesson, kaasoo u bixiyay shark Carcharhinus maou. Waxaa soo xigtay oo ku tilmaamay Cuban Felipe Poey 1861 sida Squalus longimanus. Magaca Pterolamiops longimanus ayaa sidoo kale la isticmaalay. Magaca noocyada loo yaqaan 'longimanus' wuxuu loola jeedaa cabirka baalasha laabta (longimanus wuxuu ka tarjumayaa Laatiinka sida "gacmo dhaadheer"). Shark-ka cad ee badweynta wuxuu leeyahay magacyo badan oo caan ah oo Ingiriis ah: Brown Milbert's sand bar shark, brown shark, nigano shark, oceanic white-tipped whale, iyo shark-ka cad. Xeerarka Guddiga Caalamiga ah ee Magacaabista Xayawaanka ayaa ah in guud ahaan sharaxaadda ugu horreysa ee la daabacay ay leedahay mudnaan; sidaas darteed, magaca sayniska ee saxda ah ee shark-ka cad ee badweynta waa inuu ahaadaa Carcharhinus maou. Si kastaba ha noqotee, magaca Lesson muddo dheer waa la ilaaway oo Carcharhinus longimanus ayaa weli si ballaaran loo aqbalay.  Su'aal: Yaa bixiyay warbixin ku saabsan shark cad ee badda 1861?
