Etymology: Pelagocephalus: Name 'Pelagios' meaning of the sea, in allusion to the envisioned offshore, openwater habitat and 'cephalus' or head, in allusion both to the sleek head and to the similarity of the name with that of Lagocephalus (rabbit head; appropriate for most species, but not for the two which are pelagic), one of the several genera closely related to it; coheni: Named for Dr. Daniel M. Cohen, former Director of the National Systematics Laboratory of the National
Marine Fisheries Service, Washington, D.C.
Eponymy: Dr Daniel Morris Cohen (1930–2017) was an ichthyologist who was a research associate at the California Academy of Sciences. [...] (Ref. 128868), visit book page.
