Port Jackson shark in the Flinders Marine Park

A still image of a Port Jackson shark (Heterodontus portusjacksoni) attracted to a BRUV in the Flinders Marine Park. Port Jackson sharks are well known to most divers and fishermen in southern Australia, where they commonly occur near the seafloor foraging on bottom dwelling invertebrates at night and returning to rocky caves and ledges to rest during the day. The spirally flanged egg cases of these creatures can also be observed wedged into reef crevices, where the young develop over a period of a year before hatching.
