Heterodontus portjacksoni. The Port Jackson Shark is a distinctive blunt-headed fish that has a spine in front of both dorsal fins. Port Jackson Sharks have harness-like markings which cross the eyes, run along the back to the first dorsal fin, then cross the side of the body. This pattern makes it very easy to identify the species.
