Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN] (See ETYFish); fasciatus: Latin for banded, referring to vertical dark bars on body (at least in young) (See ETYFish).

Longer snout relative to the size of the eye, head more flattened. Back brown with narrow transverse bands of darker separated spaces. Yellow spot in front of each eye above each orbit. Fins dark with narrow edgings lighter. Lower surfaces whitish (Ref. 6032).
Body shape (shape guide): elongated.
较长的吻相对于眼的大小, 头部较平的。 背面褐色的有狭窄横纹深色间隔。 在每个眼窝上面的每个眼之前的黄斑。 鳍深色且有狭窄的边缘颜色淡的。 下表面微白色的.(参考文献 6032)
Found on the continental shelf. Newbies are found on beaches of between 1 and 5 m depth, juveniles occupy inshore waters at between 15 and 50 m, and adults are found down to 50 and on upper slopes of up to 250 m in depth (Ref. 56500). Presumably feeds on crustaceans and other benthic invertebrates. Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Size at birth at or below about 39 cm. Utilized fresh-frozen and dried salted for human consumption.
栖息于大陆棚了。 新手栖息于在 1 与 5 公尺深之间的海滩, 稚鱼占领近岸水域在 15 与 50 公尺之间, 与成鱼被发现向下至 50 与在向上到的上层斜坡 250 公尺深上.(参考文献 56500) 推测为捕食甲壳动物与其他的底栖无脊椎动物。 卵胎生的, 胚胎仅以卵黄为食.(参考文献 50449) 出生时的大小在或低于大约 39 公分。 生鲜使用-冷冻与干燥盐腌供人类消费。
Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205). Migrate to the shore to give birth at the shortest time possible (Ref. 56500).西南大西洋: 巴西南部到阿根廷北部。
