( See ETYFish ) ;   quoyi: In honor of naval surgeon and naturalist Jean René Constant Quoy (1790‒1869), for his friendship, his “tireless zeal and extensive knowledgeâ€� (translation) of zoology, and for lessons and advice that have guided Fréminville in his study of science. ( See ETYFish ) . Environment: milieu / climate zone / depth range / distribution range Ecology Marine; reef-associated; depth range 3 - 40 m (Ref. 5227 ), usually 16 - 30 m (Ref. 54549 ). Tropical; 0°S - 10°S, 90°W - 71°W Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri 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. Size / Weight / Age Maturity: L m   ?   range ? - ? cm Max length : 107 cm SL male/unsexed; (Ref. 5227 ) Biology     Glossary (e.g. epibenthic) 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. Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ).
