Etymology: Heterodontus: heteros (Gr.), different; odontos (Gr.), tooth, referring to pointy teeth (for clutching prey) at front of jaws, different than rounded molar-like teeth (for grinding hard-shelled invertebrates) at the back (See ETYFish); quoyi: In honor of naval surgeon and naturalist Jean René Constant Quoy (1790‒1869), for his friendship, his “tireless zeal and extensive knowledge” (translation) of zoology, and for lessons and advice that have guided Fréminville in his study of science (See ETYFish).
Eponymy: Jean René Constant Quoy (1790–1869) was a French naval surgeon and zoologist who named many species, often with Joseph Paul Gaimard (q. [...] (Ref. 128868), visit book page.

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。

Inhabits sand flat and rocky, boulder strewn reef areas, with sand between outcroppings in inshore continental and insular waters. Rests motionless on the bottom. Is docile, non-aggressive and a poor swimmer (Ref. 5227). Nocturnal (Ref. 43278). Feeds on shellfish, crabs, and small invertebrates (Ref. 28023). Oviparous (Ref. 50449). Size at birth (for a newly hatched male) is 17 cm.
