Euclichthyidae (Eucla cods)
Etymology: Euclichthys: Greek, eukleia, -as = fame, glory (Ref. 45335); polynemus: McCulloch (1926) did not discuss the derivation of the epithet but presumably is a combination of
the Greek poly (many, very) and nema (thread) in allusion to the long, thread-like appearance of the pelvic-fin rays (see also Etyfish website, https://www.etyfish.org/?s=Euclichthys+polynemus)..
