Etymology: Acanthanectes: Greek, akantha = thorn + Greek, nekton = swimmer (Ref. 45335); rufus: Greek, acanthos = "spine" or "thorn" + Greek, nectes = "swimmer"; refers to the lateral branching spines of the dorsal fin elements; "rufus" = adjectival and is given for the species' reddish color (Ref. 35802).

Morphology | Morphometrics
Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
