Etymology: Macroramphosus: Greek, makros = great + Greek, rhamphos = beak, bill (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range 25 - 600 m (Ref. 9563), usually 50 - 350 m (Ref. 47377). Subtropical; 66°N - 43°S, 180°W - 180°E
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 4508); common length : 12.0 cm TL male/unsexed; (Ref. 4508)
Western Atlantic: Gulf of Maine to Argentina (Ref. 37039). Eastern Atlantic and Mediterranean. Indo-West Pacific. Mainly in temperate latitudes between 20° and 40°N. Presence in Somalia to be confirmed (Ref. 30573).
Found between the seabed and midwater on the lower continental shelf, over sand. Juveniles found in oceanic surface waters (Ref. 2683); adults normally live close to the bottom (normally in 50-350 m depth (Ref. 47377)). Gregarious. Juveniles feed mainly on pelagic invertebrates, mainly copepods, while adults feed on bottom invertebrates (Ref. 6732). Seems to be sympatric with Macroramphosus gracilis (Lowe, 1839) all around the world (Ref. 89357).
