Etymology: Pollimyrus: Because of Dr. Max Poll, ichthyologist + Greek, myros, -ou = the male of the morey eel; vanneer: Named after Professor Dr. Wim Van Neer (1954–) (Royal Belgian Institute of Natural Sciences, Brussels, and KU Leuven, Leuven, Belgium) for his contributions to ichthyoarchaeology in Europe and northern Africa.
Eponymy: Dr Max Fernand Leon Poll (1908–1991) was a Belgian ichthyologist, and ‘connoisseur of the fish fauna’. [...] (Ref. 128868), visit book page.
