Actinopterygii (ray-finned fishes) > Stephanoberyciformes
(Pricklefishes, bigscales and gibberfishes) > Stephanoberycidae
Etymology: Acanthochaenus: Greek, akantha = thorn + Greek, chaino = with the mouth opened (Ref. 45335). More on author: Gill.
Environment / Climate / Range
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)
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).
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.
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 models
Phylogenetic diversity index (Ref. 82805
= 1.0625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (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) .
