Anguilliformes (Eels and morays) >
Nettastomatidae (Duckbill eels)
Etymology: Facciolella: Latin, diminutive of falx, falcis = sickle (Ref. 45335); smithi: Name 'smithi' in honor of the eminent eel ichthyologist David G. Smith (1942-2024) for his
enormous contribution to the taxonomy of the world’s anguilliform fishes.
Eponymy: Dr Luigi Facciolà (1851–1943) was an Italian physician and ichthyologist who was the first to recognise and describe the Witch-Eel genus (1911) but in doing so used a preoccupied name (Nettastomella). [...] (Ref. 128868), visit book page.
