生态学
海洋 礁区鱼类; 深度上下限 3 - 40 m (Ref. 5227), usually 16 - 30 m (Ref. 54549). 熱帶; 0°S - 10°S, 90°W - 71°W
Eastern Pacific: Peru (including offshore islands) and the Galapagos Islands. There might be another Heterodontus species from Peru which is Heterodontus peruanus, but these two cannot be separated as of this time for lack of materials examined.
東太平洋: 祕魯 (包括離岸島嶼) 與加拉巴哥群島。 可能有 Heterodontus peruanus 的另一個 Heterodontus 種從祕魯, 但是無法區分兩者由於此次缺乏調查標本。
