Commonly mistaken for Port Jackson Shark, H. portusjacksoni, which has a much more distinct harness like pattern. Oviparous, with paired unusual corkscrew shaped egg cases laid, sometimes with tendrils up to 2 m long. Young approximately 22 cm at hatching. Mature adult in top photograph about 1.3 m long. Second photograph shows distinct eyebrow crest, third photograph shows egg cases entangled in black coral tree.
