The Port Jackson shark ( Heterodontus portusjacksoni) is a nocturnal, oviparous (egg laying) type of bullhead shark of the family Heterodontidae, found in the coastal region of southern Australia, including the waters off Port Jackson.
Port Jackson sharks are oviparous. During August and September, females lay 10 to 16 eggs in shallow reefs at depths of 5 to 30 meters. The egg cases are brown, spiraled structures that the females wedge into rock crevices. Females will hold an egg case in their mouth and insert it into a safe crevice.
The Port Jackson Shark occurs in southern Australian waters from southern Queensland south to Tasmania and west to the central coast of Western Australia. There are some questionable records of the Port Jackson Sharks being caught as far north as York Sound in Western Australia.
An unusual feature of the Port Jackson Shark is their spiral shaped eggs. Females can wedge them into cracks and crevices where they are held in place by the corkscrew-like grooves. Listed as least concern by the IUCN.
