Family:  Bembropidae (Duckbill flatheads)
Max. size:  28 cm TL (male/unsexed)
Environment:  demersal; marine; depth range 50 - 400 m
Distribution:  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).
Diagnosis:  Dorsal spines (total): 6-6; Dorsal soft rays (total): 14-15; Anal soft rays: 16-18. Color in alcohol light yellowish to yellowish brown dorsally, light yellowish brown to creamy brown ventrally. 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. Pectoral fin moderately rounded. Lower lobe truncate or rounded (Ref 13203).
Biology:  Found on soft bottoms of the continental shelf and feeds on crustaceans and fishes (Ref. 3656).
IUCN Red List Status: Least Concern (LC); Date assessed: 13 August 2014 Ref. (130435)
