Ammodytidae (Sand lances)
Etymology: Ammodytoides: Greek, ammos = sand + Greek, dytes = anyone that likes immersions, diving (Ref. 45335); kanazawai: Named for Takeshi Kanazawa, who provided the opportunity to the authors to examine the holotype of the species.
Eponymy: Takeshi Kanazawa of the Tokyo University of Fisheries (now Tokyo University of Marine Science and Technology) provided the authors the opportunity to examine the holotype of this species, which he had collected off the Ogasawara Islands (1995) as [...] (Ref. 128868), visit book page.
