Etymology: Idiacanthus: Greek, idia = own privative + Greek, akantha = thorn (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathypelagic; depth range 1239 - 2000 m (Ref. 58018). Deep-water; 25°S - 60°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Subtropical to temperate waters in the southern hemisphere, probably limited by the subtropical convergence. Incidentally found in sub-Antarctic waters of the Southern Ocean.

Maturity: Lm ?  range ? - ? cm
Max length : 53.0 cm SL male/unsexed; (Ref. 7249)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 55 - 63; Anal spines: 0; Anal soft rays: 37 - 42. Pelvic fins with 6 rays (females), absent in males.

Biology     Glossary (e.g. epibenthic)

Mesopelagic species (Ref. 75154). Pronounced sexual dimorphism: females are black, with well developed canine teeth, barbel and pelvic fins with six stripes. Males are dark-brown, have no teeth on maxilla and neither barbel nor pelvic fins (Ref. 47377). Apparently, females live below 500 m during the day and perform vertical migration at night to shallower depths; males always in deep water, ca 1,000-2,000 m (Ref. 5169).

Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 3.7, mean 3.1 °C (based on 311 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
