Port Jackson Shark
These harmless bullhead sharks are often found on the reefs all around South Australia. It has a relatively large head with prominent forehead ridges and dark brown harness-like markings on a lighter grey-brown body. They stay quite small, with maximum lengths recorded of about 1.7 meters (5.5 feet). They are a migratory species that travels south in the summer and returns north to breed in the winter months. It usually lives in less than 100 metres (330 feet) and can be found on stone settings on the bottom where it feeds. Since the shark is nocturnal, these sharks are usually seen in low resistance areas such as caves and overhangs during the day.
