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); californicus: -icus (L.), belonging to: California, referring to its common occurrence along the coast of California (USA) (See ETYFish).

生態學
海洋 居於水底的; 深度上下限 0 - 200 m (Ref. 55308), usually 2 - 46 m (Ref. 55308). 亞熱帶的; 40°N - 23°N, 126°W - 109°W (Ref. 55308)
Eastern Pacific: northern California, USA to the Gulf of California. At the southern part of its range, this species is sympatric with Mustelus lunulatus, but the two are readily distinguishable.
東太平洋: 美國北加州到加州灣。 在它的分佈範圍的南部，這種與 Mustelus lunulatus 重疊分佈, 但是兩者可輕易地區別。

A common inshore and offshore shark found on the continental shelves, and entering shallow muddy bays. Feeds mostly on crabs, including cancrids and grapsids, ghost shrimp, innkeeper (echiuroid) worms (Urechis), and small fish (herring and midshipmen, Porichthys). Viviparous (with a yolk-sac placenta), with 2 to 5 young in a litter. Utilized for human consumption.
一種常見的岸邊與外海的鯊魚發現於大陸棚了, 而且進入泥濘的淺水海灣。 大部份捕食螃蟹,包括 cancrids 與 grapsids ，鬼蝦, 小旅館主人 (echiuroid) 蠕蟲 ( Urechis), 與小魚.(鯡魚與 midshipmen, Porichthys) 胎生的 (具有一個卵黃囊胎盤), 有兩個到 5 幼魚在一胎。 供人類食用。
