Notacanthidae (Deep-sea spiny eels)
Etymology: Polyacanthonotus: Greek, poly = a lot of + Greek, akantha = thorn + Greek,noton = back (Ref. 45335).
Eponymy: Professor Giovanni Antonio Risso (1777–1845) (aka Joseph Antoine Risso) was an Italian-French naturalist and the first to describe deep-sea fishes as distinctive fauna and describe depth zonation with different species living in discrete depth [...] (Ref. 128868), visit book page.
