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 Identification keys | Morphology | Morphometrics

Dorsal spines (total): 16 - 18; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 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).

Estimates based on models

Preferred temperature (Ref. 123201): 19.4 - 21.9, mean 21.3 °C (based on 20 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00346 - 0.01822), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
