Port Jackson Sharks occur off southern Australia, where they live on rocky bottoms, sometimes amid seagrass. They feed on urchins, molloscs, crustaceons, and fishes. Unlike most other sharks, Port Jackosn Sharks don't need to swim to force water across their gills, but are able to pump it. This allows them to eat and breathe at the same time, and to lie still on the bottom for extended periods.

The National Zoo & Aquarium is home to 3 Port Jackson Sharks: Lola, and Clyde.
