Mori : Brotula barbata (dundat yi)
Brotula barbata, commonly known as the bearded brotula, Atlantic bearded brotula, or sugarfish, is a species of cusk-eel in the genus Brotula. It lives in the Atlantic Ocean, in depths of up to 300 meters. Its coloring ranges from olive-brown to red-brown, and it grows up to be around 50 centimeters. It has a carnivorous diet, and it is oviparous.
Brotula barbata most commonly grows up to 50 centimeters long, but has been known to grow up to nearly 100 cm. The highest published weight of a specimen was 8.5 kilograms.[2] The front of its body is somewhat deep, tapering to its rear. Its scales are smooth and relatively small, and cover its entire body. It contains 12 barbels: six on its snout and six on its chin. It has a pointed caudal fin (tail fin).[3]
Brotula barbata will sometimes have spots or freckles. It usually is brownish in color overall, with some individuals being closer to olive and others closer to red.[4]
Brotula barbata is carnivorous. It mostly feeds on bony fishes and crustaceans that live in shallow waters, including crabs and shrimp.[4] It exhibits oviparity, and lays a large amount of eggs at a time, which are gelatin-like in consistency. The species's larvae are pelagic.[1]
Brotula barbata is exclusive to marine environments. It can live up to a depth of 650 meters, but it most commonly occurs in depths from 50 – 300 m. Adults are benthopelagic, mostly inhabiting the sandy and muddy ocean floor.[3] Juveniles usually inhabit shallow coral reefs instead.[4]
Brotula barbata lives in various areas of the Atlantic Ocean, in tropical and sub-tropical climates.[5] Specifically, it occurs on the east coast of North and South America, from North Carolina down to Brazil, as well as on the west coast of Africa, from Mauritania to Angola. It is a common species throughout its range. Although it is sometimes a bycatch in fisheries, there are no major threats to the species, and it is therefore listed as "Least Concern" by IUCN.[1]

Presenta un corpo dalla forma piuttosto tozza, compresso ai fianchi, con coda anguilliforme (pinne dorsale, caudale e anale unite). Il muso è munito di barbigli sensibili, e anche le pinne ventrali sono trasformate in due filamenti ramificati.
Nei luoghi d'origine è oggetto di pesca per l'alimentazione e per la pesca sportiva.

Brotula barbata is een straalvinnige vis uit de familie naaldvissen (Ophidiidae). De vis kan maximaal 94 cm[2] lang en 8520 gram[2] zwaar worden.
De slakdolf is een zoutwatervis. De vis leeft hoofdzakelijk in de Atlantische Oceaan. De diepteverspreiding is 0 tot 650 m.[2]
De slakdolf is voor de visserij van beperkt commercieel belang. In de hengelsport wordt er weinig op de vis gejaagd.

ニシイタチウオ（西鼬魚、学名：Brotula barbata）は、アシロ目アシロ科に分類される魚類の1種。イタチウオ属のタイプ種である。
ニシイタチウオは、大西洋の北回帰線と南回帰線に挟まれた熱帯海域に分布する海水魚である[2]。 イタチウオ属の種の中で大西洋に分布するは本種のみである。 海底付近を遊泳し餌を探し回る底生遊泳魚である。 主に大陸棚および大陸斜面上部の水深50-300mの砂泥底に生息するが、水深650mで採集されたこともある。稚魚は浅海の岩礁域やサンゴ礁域で採集される。仔魚は沖合の表海水層で採集される。卵生。卵は楕円形で、寒天質の卵嚢に包まれた状態で産まれ海中を浮遊する[2]。
ニシイタチウオは全長50cmほどの個体が多いが、最大で全長94cmにまで達する[2]。 体が細長く、尾部は側扁し、後端が尖る。背鰭と臀鰭が尾鰭と繋がっている。 背鰭軟条数は109-117、臀鰭軟条数は86-90。背鰭と臀鰭は棘条を欠く。体表は全体が微小な円鱗で覆われる。上顎と下顎にそれぞれ三対の髭がある[2]。 頭長は体長の23-25%[1]。 鰓条骨数は8。中基鰓骨上に歯がない。第1鰓弓の発達した鰓耙数は4以下[2]。 腹鰭は2軟条で眼の後方のほぼ前鰓蓋骨下方にある[3]。 体色は褐色。 背鰭と尾鰭は暗色で縁辺ほど色が黒っぽくなる[2]。
ニシイタチウオは、アフリカの熱帯大西洋沿岸諸国で漁業の対象であり、1996年には世界で368トンの漁獲が報告された。主に大陸棚での底曳き網漁で漁獲される。市場には鮮魚および干物、塩漬けなどの形で出回る[3]。
