Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN] (See ETYFish); widodoi: In honor of the late Johannes Widodo (1944-2005), Research Institute of Marine Fisheries (Jakarta, Indonesia), “whose research on the shark and ray fisheries of Indonesia has provided important baseline data for this important faunal region” (See ETYFish).
Eponymy: Dr Johannes A O Widodo (d: 1944) is a biologist at the Research Institute of Marine Fisheries, Jakarta, Indonesia, and has done much work on the shark and ray fisheries of Indonesia. [...] (Ref. 128868), visit book page.
