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.
在哪里、什么时候能见到
"常驻"表示在该目的地潜水时大多数情况下都能遇见它们；"季节性"表示在所列月份内可靠出现；其他任何情况都是意外惊喜，而非计划中的保障。

深入了解
栖息地: Sandy gutters, bommies, and cave mouths along rocky reefs of the Australian coast; the same air-gulping hover as its overseas populations
分布范围: 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
习性: 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.
食性: Reef and pelagic fish, rays, and small sharks, taken mostly at night
体型: 通常约 2.5 m; 记录深度可达 3.2 m (total length).
与它相处时的行为守则
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.
保育
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.
