بوم شناسي
دريايي موجوداتی که در محدوده وسیعی از آبهای آزاد از نزدیک بستر و یا روی کف بستر، در قسمت های میان آبی تا سطح آب و در برخی گونه ها با قابلیت پرواز، زندگی و تغذیه می کنند.; تغييرات عمق 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.
Length at first maturity / Size / Weight / سن
بلوغ: Lm ?, range 12 - ? cm
Max length : 15.2 cm TL جنس نر / بدون خواص جنسي; (Ref. 41039)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 11; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 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).
