0-275m
The Port Jackson Shark is easily identified by its distinctive dark brown or black harness-like markings that cross its eyes and run down its back. Its blunt, pig-like snout is another key feature. They have a small mouth located well forward of the eyes. The presence of a spine at the front of each of their two dorsal fins is also diagnostic, as is their generally stout body shape.

Heterodontidae
The Port Jackson Shark is a favourite amongst divers in Southern Australia! These charismatic sharks are typically found resting on the seafloor or slowly cruising along rocky reefs, often in caves or under ledges. Their distinctive harness-like markings and pig-like snout make them easily recognizable. While they are sharks, they're generally quite docile and pose little threat to divers, making them a fantastic subject for underwater photography. Keep an eye out for their unique spiral-shaped egg cases attached to seaweed or rocks - a sure sign of a healthy population. Encountering these gentle giants is a memorable experience, offering a glimpse into the diverse and fascinating world beneath the waves. These sharks are most active at night, when they hunt for invertebrates on the seafloor. During the day, they often gather in groups, offering divers a chance to observe their social behaviour. While generally shy, they can be habituated to divers over time, sometimes even allowing close approach. Respect their space and avoid harassing them, and you'll be rewarded with an unforgettable encounter.
