Classification / Names ຊື່ສາມັນ | ຄຳສັບຄ້າຍຄືກັນ | Catalog of Fishes(ຕະກຸນ, ຊະນິດ) | ITIS | CoL | WoRMS | Cloffa

ກຸ່ມປາກະດູກອ່ອນ (ເຊັ່ນ: ປາສະຫລາມ, ປາຜາໄລ) (sharks and rays) > Heterodontiformes (Bullhead and horn sharks) > Heterodontidae (Bullhead, horn, or Port Jackson sharks)
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);  francisci: Of Francisco, probably referring to San Francisco (city and/or bay), California, USA (although its range does not extend that far north of its type locality, Monterey Bay). (See ETYFish).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Sluggish, nocturnal, and mostly solitary species. Inhabit rocky bottoms, kelp beds, sandy draws between rocks, on sand flats, deep crevices and small caves and also large underwater caverns. Adults tend to return to the same resting place every day (Ref. 43278). Feed on benthic invertebrates, especially sea urchins, crabs and probably abalone, also fishes. Oviparous (Ref. 50449). May bite back when harassed. Has broad muscular paired fins used as limbs for clambering on the bottom. Catch reduced to fish meal; fin spines used in production of jewels.

Oviparous (Ref. 205). Distinct pairing with embrace (Ref. 205). Courtship starts when the male chases the female, then when both are ready, they drop to the bottom (Ref. 43278). During courtship and prior to copulation, the male bites and wraps its body to the female pectoral fin, body, tail, and gills (Ref. 51127, 49562). The male then inserts a single clasper in the female's cloaca; copulation lasts 30 to 40 min. After one or two weeks later, the eggs are laid in about 11 to 14 intervals for 4 months which were deposited under rocks or in crevices, as was observed in nature. In captivity, the female drops the eggs on the bottom where the contents of the egg cases maybe eaten by these sharks; the eggs are hatched in 7 to 9 months. The young begin to feed one month after hatching (Ref. 43278).
