Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Stomiiformes (Lightfishes and dragonfishes) > Stomiidae (Barbeled dragonfishes) > Malacosteinae
Etymology: Malacosteus: Greek, malakos = soft + Greek, osteon = bone (Ref. 45335);  australis: Name from Latin austral, meaning southern, for the geographical range of this species..

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

Marine; bathydemersal; depth range 500 - 2000 m (Ref. 78501). Subtropical; 25°S - 45°S

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

Circumglobal: subtropical and temperate waters of the southern hemisphere, 25°-45°S and equatorial Indian Ocean and Indo-Australasian Archipelago.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 16.6 cm SL male/unsexed; (Ref. 78501); 19.2 cm SL (female)

Short description Morphology | Morphometrics

Dorsal soft rays (total): 16-21; Anal soft rays: 18 - 23; Vertebrae: 45 - 51. This species possess the following characters: in male, postorbital photophore (PO) 3.7-6.4% upper jaw length (UJL), 0.9-1.7% SL; female PO 2.5-4.4% UJL, 0.6-1.2% SL; IP photophores 5-7 in 3-7 clusters (Ref. 78501).

Biology     Glossary (e.g. epibenthic)

Only a few were caught above 500 m, thus it appears that this species does not regularly migrate on a diel basis out of the mesopelagic. With its large accessory orbital photophore (AO), this species likely uses this in employing a far-red visual system as part of its foraging strategy (Ref. 78501).

Estimates based on models

Preferred temperature (Ref. 123201): 1.2 - 2.1, mean 1.8 °C (based on 558 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00157 - 0.01056), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
