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); canis: Of islands, referring to occurrence at several Caribbean islands (Cuba, Jamaica, Grand Cayman, Puerto Rico, Nevis Island, Sint Eustatius, the Bahamas and Bermuda), where it appears to be the only species of Mustelus. (See ETYFish).

生态学
海洋; 半咸淡水 居于水底的; 海洋洄游的 (Ref. 51243); 深度上下限 0 - 800 m (Ref. 55584), usually 18 - 200 m (Ref. 55309). 亞熱帶的; 46°N - 44°S, 98°W - 31°W
Western Atlantic: Massachusetts to Florida (USA), northern and western Gulf of Mexico, Venezuela, Cuba, Jamaica, Barbados, Bermuda, Bahamas; southern Brazil to northern Argentina; also western Gulf of Mexico and Antilles (Ref. 26938). Northwest Atlantic: Canada (Ref. 5951). Allopatric with Mustelus mustelus and sympatric with Mustelus norrisi. One of the two new allopatric species of canis- norrisi-like smooth-hounds in this region is often confused with this species (Ref. 244). The subspecies Mustelus canis insularis, occurring at several Caribbean islands, was identified by Heemstra (Ref. 27770).

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 99.8, range 95 - 100 cm
Max length : 150 cm TL 雄鱼/尚未辨别雌雄; (Ref. 244); common length : 100.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 6077); 最大体重: 12.2 kg (Ref. 40637)
A small, slim shark. Well-serrated dorsal fins, second nearly as large as first (Ref. 26938).
一种小的, 瘦的鲨鱼。 深锯齿状的背鳍, 第二个几乎与第一个一样大.(参考文献 26938)
Found on continental and insular shelves and upper slopes, ranging from shallow inshore waters and the intertidal to 200 m, occasionally down to 579 m (Ref. 244). Occasionally found in freshwater. It is doubtful that this species can live in fresh water for an extended period of time (Ref. 244). Active swimmer and bottom feeder (Ref. 27549). Swims in packs or schools (Ref. 27549). Feeds on large crustaceans, mainly crabs, but also heavily on lobsters (Homarus) (Ref. 244). Probably non-territorial. Off the Atlantic coast of the USA, this species is migratory (Ref. 244). Viviparous (with a yolk-sac placenta), with 4 to 20 young in a litter. Longevity given as 7 years (Ref. 775) but appears too low. Utilized fresh, dried-salted, and smoked (Ref. 9987).
栖息于大陆架与岛屿棚与被范围从沿岸浅水区水域与潮间带到 200 公尺的上层斜坡了, 偶然地向下至 579 公尺.(参考文献 244) 偶然地发现于淡水了。 它是可疑的这种能生活于淡水一长段时间.(参考文献 244) 吃大的甲壳动物, 主要地螃蟹, 也经常捕食龙虾 ( Homarus).(参考文献 244) 可能非领域性。 美国的大西洋海岸外, 这种是回游的.(参考文献 244) 胎生的 (具有一个卵黄囊胎盘), 有四个到 20 幼鱼在一胎。 寿命被估为 7 年 (参考文献 775) 但是显得太低的。 生鲜使用，乾燥盐腌, 而且烟熏.(参考文献 9987)
