Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino benthopelagico; distribuzione batimetrica 1655 - 5397 m (Ref. 58018). Deep-water; 40°N - 57°S, 77°W - 164°W
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.
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm ?, range 12 - ? cm
Max length : 15.2 cm TL maschio/sesso non determinato; (Ref. 41039)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11; Spine anali: 1; Raggi anali molli: 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).
Body shape (shape guide): fusiform / normal.
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).
