海洋 居於水底的; 深度上下限 20 - 345 m (Ref. 86942). 亞熱帶的; 40°N - 19°N, 112°E - 141°E
Northwest Pacific: China, Taiwan, Korea, and Japan. Nominal records from Ambon, Indonesia (unconfirmed and based on a specimen close to if not identical to Hemitriakis abdita) and New Caledonia (Ref. 13563).
西北太平洋: 中國，台灣，韓國與日本。 來自安彭，印尼 (未被證實的而且以一件標本為依據接近如果不與 Hemitriakis abdita 完全相同) 與新加勒多尼亞的分類命名紀錄.(參考文獻 13563)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 91.5, range 81 - 102 cm
Max length : 110 cm TL 雄魚/尚未辨別雌雄; (Ref. 244); 120.0 cm TL (female); 最大年齡: 15 年 (Ref. 9031)
Occurs close inshore and offshore down to at least 100 m depth. Presumably feeds on small fishes, cephalopods and crustaceans. Ovoviviparous, with 8 to 22 young in a litter. Size at birth about 20 to 21 cm. Utilized for human consumption.
生存近岸，而且外海向下至至少 100 公尺深。 推測為捕食小魚，頭足類動物與甲殼動物。 卵胎生的,8 到 22 幼魚在一胎。 出生時的大小大約 20 到 21 公分。 供人類食用。
