Interesting Facts:

Port Jackson sharks are normally found in tropical and temperate waters in depths normally less than 100m, but can sometimes be found as deep as 275m. 

Port Jackson Sharks inhabit rocky environments on or near the bottom. But may also be found in muddy and sandy areas, or where seagrass occurs. They usually feed on sea urchins, molluscs, crustaceans and small fish.

They have a small spine on the front edge of each of their dorsal fins.
