Actinopteri (ray-finned fishes) > Myctophiformes
(Lanternfishes) > Myctophidae
(Lanternfishes) > Lampanyctinae
Etymology: Lampanyctus: Greek, lampas, -ados = torch + Greek, nykte = night (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 60 - 1150 m (Ref. 36121). Deep-water; 42°N - 37°S, 82°W - 153°W
Tropical and subtropical waters of the Atlantic, Indian and Pacific oceans. Eastern Atlantic: disjunct distribution between 35°N-27°S and in Agulhas Water pockets (absent over the upwelling region between 17°N-9°N, east of 30°W). Western Atlantic: disjunct distribution between 42°N-10°S. Indian Ocean: between 8°N-0°. Western Central Pacific: Philippines. Considerable differences between Atlantic and Indo-Pacific material suggests that there may be more than one species involved (Ref. 36121).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 15 - ? cm
Max length : 23.7 cm SL male/unsexed; (Ref. 36121)
Oceanic (Ref. 4066), found between 650-1,000 m during the day; between 60-225 m at night (maximum abundance (mainly juveniles) at 100 m) (Ref. 4479). Mesopelagic (Ref. 58302). Uncommon species (Ref. 36121).

Estimates based on models
Preferred temperature (Ref. 115969
): 7.7 - 18.6, mean 11.9 °C (based on 891 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00216 - 0.01160), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
