N2  - SCUBA observations show that Port Jackson sharks repeatedly visit specific resting sites on ocean reefs at South Bondi (New South Wales) and, when disturbed, move directly from one site to another. The sharks also use specific resting sites in Sydney Harbour and, when transferred by boat to different localities within the harbour, up to 3 km away, return to their original resting sites. The sharks migrate from as far south as Tasmania to Sydney Harbour to lay their eggs in specific sites. Speculative extrapolation from the above observations suggests that Port Jackson sharks must have a highly developed spatial memory.
