Ecologia
marino batipelagico. Deep-water; 35°S - 49°S, 54°W - 154°W
Atlantic Ocean: roughly between 35°-20°N; near 30°W between 20°-25°S. Also known from the Indian and Pacific oceans.
Length at first maturity / Size / Peso / Age
Maturity: Lm 15.0, range 14 - 16.3 cm
Max length : 17.2 cm SL maschio/sesso non determinato; (Ref. 4468)
Spine dorsali (totale) : 0; Spine anali: 0. Barbel length less than 20% of standard length; barbel with 5 branches apparently arising together from stem; lateralmost pair of branches, which actually arise from base of mediolateral pair, usually shortest; mediolateral pair usually longest; diameter of stem distal to branches greater than that proximal to branches; stem solidly pigmented, pigment extending onto dorsal surface of terminal bulb; terminal bulb elongate and with an unpigmented tip usually directed dorsally; swollen ventrally, its length 2.0 - 2.5 times its thickness; a single terminal filament arising ventral to bulb tip, usually about as long as distal barbel, but occasionally minute.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.3 ±0.8 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (11 of 100).
