Overview

Found singly or in shivers, resting during the day, in caves, under ledges and on sandy bottoms, in shallow temperate waters, of coastal rocky reefs, dispersing at night to hunt for food. The eggs of these sharks are a distinctive spiral shape.
They feed nocturnally on crustaceans, fish, molluscs and sea urchins.
Western Pacific - Southern Australia

These sharks have no anal fin but have spines on the leading edge of the two dorsal fins.
Port Jackson Sharks are not considered dangerous unless threatened and then can give a painful bite!

    The "horns" above the eyes make the Port Jackson shark a funny looking creature. Their eggs also look weird. If you can dive under the sea near Sydney, often you can meet with one. They can be found in the kelp forests under the ocean.
