Etymology: Acanthanectes: Greek, akantha = thorn + Greek, nekton = swimmer (Ref. 45335); hystrix: Greek, acanthos = "spine" or "thorn" + Greek, nectes = "swimmer"; refers to the lateral branching spines of the dorsal fin elements; and "hystrix" = generic name for the African porcupine, referring to the fish's prickly appearance (Ref. 35802).

Short description
Morfologia | Morfometria
Spine dorsali (totale): 16 - 18; Raggi dorsali molli (totale): 9-10; Spine anali 1; Raggi anali molli: 18 - 19.
Adults are found in shallow to deep reefs, 10-24 m (Ref. 35802). 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).
