Sharks
Grey Nurse Shark
Carcharias taurus · Cartilaginous fish — family Odontaspididae
Australia's grey nurse is the same ragged-toothed species divers meet on North Carolina wrecks and Aliwal's caves, but its story here is distinct and cautionary. Labeled a killer on looks alone, it was speared toward oblivion by the 1970s before becoming one of the world's first protected sharks. Today small aggregations still trace slow ovals through gutters at a handful of east-coast sites, gliding among divers with prehistoric calm. The listed destinations in this atlas brush only the edges of its range — the celebrated aggregation reefs lie along the New South Wales and southern Queensland coast — so treat any sighting elsewhere in Australia as a bonus, not a plan.
어디서 언제 볼 수 있나
"상주종"은 해당 다이빙 포인트에서 대부분의 다이빙 시 만날 수 있다는 의미이며, "계절종"은 표기된 월에 안정적으로 출현한다는 뜻입니다. 그 외의 생물은 보너스로 여기세요 — 계획의 근거로 삼지 마세요.

이해하기
서식지: Sandy gutters, bommies, and cave mouths along rocky reefs of the Australian coast; the same air-gulping hover as its overseas populations
범위: Australian name for the sand tiger shark, Carcharias taurus. Two Australian populations: a small east-coast population from southern Queensland through New South Wales, and a distinct, poorly known west-coast population
행동 특성: Days are spent circling slowly in traditional gutters and around pinnacles in loose aggregations, mouths bristling, bodies nearly still in the surge. Individuals return to the same handful of sites for years, which concentrates both divers and risk in the same places.
먹이: Reef and pelagic fish, rays, and small sharks, taken mostly at night
크기: 보통 2.5 m; 최대 기록 수심 3.2 m (total length).
이 생물 주변에서의 행동 요령
Australian critical-habitat rules are specific: no blocking gutters or cave entrances, no chasing or touching, approach along the side rather than head-on, keep group sizes modest, and no scooters or feeding at aggregation sites.
보존
The east Australian population is listed Critically Endangered nationally, numbering in the low thousands at best; protected since 1984 in NSW, with designated critical-habitat sites carrying enforceable approach rules.
