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);  portusjacksoni: Of Port Jackson, Sydney, New South Wales, near Botany Bay, type locality. (See ETYFish).

生物學特性     字彙 (例如 epibenthic)

A common shark of the continental shelves (Ref. 9838), from close inshore at the intertidal zone to 275 m (Ref. 6871). Segregates by sex and maturity stage (Ref. 6871). Nocturnal, hides in caves and rocky gullies during the day (Ref. 6871). Feeds on benthic invertebrates, primarily echinoderms (Ref. 247). Oviparous (Ref. 50449). Eggs with spiral flanges but lack tendrils (Ref. 6871). Undergoes yearly migrations to spawning sites during breeding season (Ref. 247). Considered harmless to people, but can deliver a painful nip when provoked (Ref. 247).

一種常見的大陸棚 (參考文獻 9838) 的鯊魚,275 公尺的從岸邊的潮間帶.(參考文獻 6871) 藉著性別與成熟階段分離。 (參考文獻 6871) 夜行的, 躲在洞穴與岩石的小峽谷中在白天期間.(參考文獻 6871) 吃底棲的無脊椎動物, 主要地棘皮動物.(參考文獻 247) 卵生的.(參考文獻 50449) 卵有螺旋形之物邊緣但是缺乏捲鬚.(參考文獻 6871) 在繁殖季節的時候歷經對產卵區的每年迴游。 (參考文獻 247) 被認為是對人無害, 但是能傳送一個令人痛苦的咬當被激怒時.(參考文獻 247)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Oviparous. Distinct pairing with embrace (Ref. 205). Undergoes yearly migrations to breeding sites. Females lay about 10 to 16 (commonly 10-12) eggs in rock crevices on shallow sheltered reefs at depths of 1-5 m (rarely 20-30 m) during August and September (rarely in July and October). In captivity, females lay 2 eggs a day every 8-17 days. Eggs are hatched after 9-12 months and young then move into nursery areas in bays and estuaries. After the breeding season, males move into deeper waters followed by the females in late September or October.西太平洋: 澳洲 (包括西澳大利亞) 南部而且一個記錄來自紐西蘭。 來自南非的 Heterodontus bona-spei 可能歸屬於這種。
