Port Jackson Shark Heterodontus portusjacksoni
Port Jackson shark (PJ) sitting under an overhang lined with colourful encrusting sponges at Oak Park a dive site near Cronulla south of Sydney, about 10m depth. These small sharks come inshore to breed in the winter time, the females lay a large spiral egg casing and place it in crevices to hatch. About a 1 - 1.5m long they are harmless and eat crustaceans and similar prey grinding them up with their teeth. They lie about under overhangs and in crevices and caves during the day.
