Environment / Climate / Range Ecology

Marine; benthopelagic; depth range 1655 - 5397 m (Ref. 58018).   Deep-water; 40°N - 57°S, 77°W - 164°W

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 12 - ? cm
Max length : 14.1 cm SL male/unsexed; (Ref. 50895)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 1; Anal soft rays: 9 - 10. Body scales are spiny (Ref. 37108). Body elongated, almost cylindrical, somewhat compressed (Ref. 10920). The snout protrudes forward above upper jaw, its length 3.4-4.4 times in head length, eyes fairly small, upper jaw extends beyond the posterior border of the eye. Dorsal and anal fins are opposite one another (Ref. 10920).

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

Atlantic, Indian and Pacific: in subtropical and temperate waters (Ref. 50895). In the Indian Ocean known localities include the Madagascar Ridge (Ref. 51654) and the West Australian Ridge, Naturalist Plateau.

Biology     Glossary (e.g. epibenthic)

Adults probably benthopelagic (Ref. 51654). Larvae taken at 30 m (Ref. 51654). Benthic crabs Malacostraca were found in the stomachs of 3 specimens SL 8.5-9 cm from Madagascar Ridge (Ref. 10920).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (-0.16178 - 0.18422), b=3.04 (2.95 - 3.13), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.60 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax > 3; K=0.41).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
Price category (Ref. 80766):   Unknown.
