[New Latin Dugong, genus name, ultimately (partly via French dugon) from dugung, recorded as a local word for the dugong on the Moluccan island of Leti by Ernst Christoph Barchewitz (1687-1758), German travel writer and administrator for the Dutch East Indies Company, perhaps a misreading (with g for y) of *duyung, representing a local pronunciation of standard Malay duyong; akin to Tagalog duyong, dugong, and Malagasy trozona, whale, all from Proto-Malayo-Polynesian *duyuŋ, dugong.]
