Bembropidae (Duckbill flatheads)
Etymology: Bembrops: Greek, bembras, -ados = a kind of anchovy m+ Greek, ops = appearance (Ref. 45335); heterurus: Specific name probably from the Greek 'heteros' meaning different and 'oura' meaning tail..
Environment: milieu / climate zone / depth range / distribution range
生態学
海 底生の; 深さの範囲 50 - 400 m (Ref. 6948), usually 80 - 200 m (Ref. 47377). Deep-water; 12°N -
Western Atlantic: off Rio de Janeiro, Brazil to Uruguay. Eastern Atlantic: Mauritania to the extreme northern waters of Namibia (Ref. 6948, 27121). The eastern Atlantic form referred to as Bembrops heterurus is unlikely to be conspecific with the Brazilian form, thus further taxonomic study is needed to clarify this situation (Ref. 6948).

Upper lobe of caudal fin elongated at an acute angle. Snout relatively short, 1.0-1.4x eye diameter. Scales on lateral and dorsal surfaces of snout including area in front of eye. Upper jaw extending behind anterior margin of eye but not reaching its mid-line. Maxillary tentacle short. Lateral line descending gradually along dorsal edge of pectoral fin, separated from origin of first dorsal fin by 4 or 5 rows of scales, from origin of anal fin by 6 or 7, and from insertion of anal fin by 3-5.
