Quick Summary

The Port Jackson shark is a small, harmless shark belonging to the genus Heterodontus. These sharks are found in the coastal waters of Australasia and are characterized by their broad heads, short snouts, and small mouths. Their teeth are adapted for crushing and grinding, and they primarily feed on mollusks, crabs, and sea urchins.12

The Port Jackson shark is one of about 11 species within the bullhead shark family, Heterodontidae. While most bullhead shark species have healthy populations, the Port Jackson shark (H. portusjacksoni) can grow up to 1.65 meters (5.4 feet) in length. Unlike some other shark species, bullhead sharks are not considered dangerous to humans.23
